MID Server properties
Properties control the behavior of all MID Servers or a particular MID Server.
 |
The MID Server properties are in the MID Server Property [ecc_agent_property] table and can be accessed by navigating to . To set these properties, you must add them, if they are not already present.
MID Server properties
- com.glide.closure_max_rows_per_table
- Sets the maximum number of rows allowed in a table. This property is not visible by
default and must be added.
- Type: integer
- Default value: 200000
- concurrent.dist.download
- Sets the number of concurrent MID Server auto-upgrades permitted by the instance. The
default value of this property is 2, which allows the MID Server to use 2 of the 4
semaphores available on the instance for upgrading. If your instance has more than 4 INT
semaphores, you can increase the value in this property to allow more concurrent
upgrades.
- Type: integer
- Default value: 2
- glide.stored_proc.data_type.validation
- Stops validation of data types in stored procedure parameters. Use this property if
you use Orchestration to run a stored procedure on MySQL, Oracle DB, and MS-SQL
databases and you want to avoid performing data type validation. Restart the MID Server
service after you change the value of this property.
- Type: true | false
- Default value: false
- mid.discovery.max_ci_count_per_page
- Defines the maximum CI count per page.
- Type: integer (bytes)
- Default value: 500
You can also configure this as a configuration parameter on a individual MID Server.
- mid.discovery.max_related_count_per_page
-
- Type: integer
- Default: 100
- mid.discovery.max_relation_count_per_page
- Splits the payload based on the number of relations in
it.
- Type: integer
- Default: 10000
- mid.discovery.max_total_items_size_per_page
- Splits the payload based on the size of the items.
- Type: integer
- Default:
- mid.aws.sts.assume_role.disable_credential_caching
- Set this property to true to prevent the caching of temporary
credentials for Cloud Discovery. For more information, see Access setup for AWS service
accounts
Access setup for AWS service accounts.
- Type: true | false
- Default: false
- mid.aws.sts.assume_role.credential_ttl_minutes
- Set the number of minutes you want to cache temporary credentials for Cloud Discovery. For more information, see Access setup for AWS service
accounts
Access setup for AWS service accounts.
- Type: integer
- Default: 60
- mid.ca.certificate.api.request.retry.count
- Indicates how many times the Certificate Import query will retry after the rate limit
has occurred.
- Type: integer
- Default: 3
- mid.ca.certificate.api.request.retry.interval
- Used to delay Certificate import from CAs when the rate limit has occurred.
- Type: integer
- Default: 30000
- mid.cloud.discovery.bypass.proxy
This configuration parameter accepts a comma separated list of DNS/IP addresses of proxy servers. The listed proxy servers are bypassed during Cloud Discovery. To bypass proxies on multiple cloud service providers (such as AWS or Azure), a separate MID Server must be set up for each provider. Otherwise, the MID Server proxy configuration is followed normally.
- Type: string
- Default value: none
- mid.discovery.file_transfer_protocol
- Used to determine the file transfer method used for probes or patterns.
- Type: Choice (SCP or SFTP)
- Default: SCP
- mid.discovery.max_pattern_payload_size
- Defines the maximum overall payload size for the payload of results that come from
patterns.
- Type: integer (bytes)
- Default value: 50000000
You can also configure this as a configuration parameter on a individual MID Server.
- mid.discovery.max_payload_size
- Specifies the maximum string length of Discovery results that the MID
Server sends to the instance. If the Discovery probe results exceed the
limit, the MID Server discards them and returns a warning message.
For probes, this applies only to those probes where the Used by Discovery field is true. For patterns, this applies to the Horizontal Pattern probe.
Set the value to any negative number to disable the payload limit and allow payloads of any size to be sent to the instance. For example, -1.
- Type: integer (bytes)
- Default value: 5000000
You can also configure this as a configuration parameter on a individual MID Server.
- mid.discovery.multiprobe.skip_others_on_error
- Prevents probes in a multi-probe from iterating through available credentials
when another member probe has already failed or timed out. If this property is set to
false, each probe in the multi-probe attempts to connect to the
target with the same invalid credentials. This condition results in longer probe
execution times on the MID Server.
This property is not visible by default and must be added to the sys_properties table to change the value.
- Type: true | false
- Default value: true
- mid.discovery.aws_ssm.kms_key_name
-
Using a dedicated key enhances security by verifying that applicative credentials are encrypted and securely retrieved at runtime, without being exposed in plain text. This step is optional and only necessary if you plan to use applicative credentials during discovery. To configure the MID Server to support secure credential handling during SSM Agent discovery, set the mid.discovery.aws_ssm.kms_key_name property to the name of the AWS KMS key.
- Type: string
- Default value: none
- mid.discovery.aws_ssm.kms_key_region
-
Using a dedicated key enhances security by verifying that applicative credentials are encrypted and securely retrieved at runtime, without being exposed in plain text. This step is optional and only necessary if you plan to use applicative credentials during discovery. To configure the MID Server to support secure credential handling during SSM Agent discovery, set the mid.discovery.aws_ssm.kms_key_region property to the region where the key is located.
- Type: string
- Default value: none
- mid.discovery.aws_ssm.s3_bucket_name
-
Because the SSM Run Command console has a 24,000-character limit, results that exceed this limit must be stored in and retrieved from an S3 bucket. For Put File commands, the S3 bucket also serves as a transfer point between the MID Server and the AWS environment, enabling file delivery to target devices via SSM. To configure the MID Server to support these S3-based operations, set the mid.discovery.aws_ssm.s3_bucket_name property to the name of the S3 bucket used for SSM Agent discovery.
- Type: string
- Default value: none
- mid.discovery.aws_ssm.s3_bucket_region
-
Because the SSM Run Command console has a 24,000-character limit, results that exceed this limit must be stored in and retrieved from an S3 bucket. For Put File commands, the S3 bucket also serves as a transfer point between the MID Server and the AWS environment, enabling file delivery to target devices via SSM. To configure the MID Server to support these S3-based operations, set the bucket’s region in the mid.discovery.aws_ssm.s3_bucket_region property.
- Type: string
- Default value: none
- mid.discovery.aws_ssm.linux.fallback_root_user
-
When the glide.discovery.enable_ssm property is enabled, AWS SSM Discovery on Linux defaults to using the root user for command execution. If you prefer not to configure alternate user credentials on your EC2 instances, you must enable the mid.discovery.aws_ssm.linux.fallback_root_user property to allow fallback to root execution. When enabled, it automatically creates a record in the AWS SSM Instance Users [aws_ssm_instance_user_credentials] table with the user name root. However, if you leave this property set to false, you must configure non-root credentials to run Discovery commands.
- Type: true | false
- Default value: false
- mid.eccq.max_payload_size
- Specifies the maximum string length of a payload that the MID Server sends to the
instance. The MID Server verifies the size of the payload before sending it to the
instance. If the payload size exceeds the limit, the MID Server discards it and returns
an error message in the payload.
- Type: integer (bytes)
- Default value: 20000000
You can also configure this as a configuration parameter on a individual MID Server.
- mid.http_classy.allow_credentials_over_http
- Enables the HTTP Classify probe to send credentials over the HTTP protocol during discovery.
- Type: true | false
- Default value: false
警告:Enabling this setting can expose credentials to security risks, such as man-in-the-middle (MitM) attacks. Therefore, it’s strongly recommended to keep this property set to false and use HTTPS whenever possible. - mid.install_server.base_uri
Modifying this system property requires maint privileges. The MID Server uses the value provided as the base URL when making requests for update files.
- Type: string
- Default value: https://install.service-now.com
- mid.jdbc.datastream.max.record.size
- Specifies the maximum record size in KB.
- Type: integer
- Default value: 64
- Maximum value: 128
- mid.jdbc.datastream.fail.when.attachement.limit.exceeded
- Specifies if the data up to 4GB (four attachments, each of size 1GB) can be retrieved
from the RDBMS. By default, a flow or action fails with an error, when there is data of
more than 4GB to be retrieved. Set value to false to retrieve
data of size 4GB without an error.
- Type: string
- Default: true
- mid.keystore.max_backups
- Specifies the maximum number of backups from manual key store operations through the
manage_certificate script. If it is 0 or negative, no backup
will be made.
- Type: Integer
- Default value: 3
- mid.keystore.max_live_backups
- Specifies the maximum number of live backups from running MID server. If it is 0 or
negative, no backup will be made.
- Type: Integer
- Default value: 2
- mid.keystore.backup_overwrite_timespan
- Specifies the number of seconds from the current backup time to determine if a the
most recent backup in that time span should be replaced by the new one instead of
creating a new backup and so removing the oldest backup, should the number of backups
exceed the maximum limit.
- Type: Integer
- Default value: 60
- mid.log.command_audit.enable
- Enables the MID Server command audit log.
- Type: string
- Default value: false
- mid.powershell.target_base_dir
- Specifies the location of the target base folder used for Discovery using WMI. If
another network share is mounted on each Window's target, the folder may be changed by
updating this property.
- Type: string
- Default value: admin$\temp
- mid.probe.collect_debug_info
An optional property to collect debug information. If this property is set to true, the probe collects credential debug information when it runs and puts that information in the payload of ECC input message. It doesn't affect how Discovery works.
- Type: true | false
- Default value: false
- mid.probe.use_legacy_forward_dns
- Enables the legacy DNSNameResolver probe and disables the default DNSNameResolver
probe. See Probes used by Orchestration for
more information.
- Type: true | false
- Default value: false
- mid.probe.use_legacy_reverse_dns
- Enables the legacy DNS probe and disables the default DNS probe. If you experience
problems with the features of the default DNS probe, use this property to disable those
features. The default DNS probe's features include being lightweight and faster due to
executing in parallel, while the legacy probe is throttled by the MID Server because it
executes in serial. The default probe utilizes DNS lookup by the MID Server host OS to
make use of the OS maintained DNS cache, while the legacy probe does not. Consequently,
after a DNS lookup by the default probe fails in Windows systems, the OS also tries
looking up by NETBIOS name.
- Type: true | false
- Default value: false
- mid.process_flow.log_listener.max_size
- Sets the maximum size in bytes of memory available to save log messages for Workflow Studio actions running on a MID Server. The MID Server stores up to the limit in memory and discards additional log
messages, then sends the messages back to the instance along with the execution plan.
- Type: integer (bytes)
- Default value: 10485760
- mid.property.jdbc_operations
- Tells the JDBCOrchestrationProbe what JDBC operations it is allowed to execute. Edit
this property value to allow JDBC Orchestration activities to perform more operations.
All operations are comma separated. Select a MID Server in the MID
server field to define specific operations for that MID Server, or leave
the field empty to apply the list of operations to all MID Servers. This property
requires the Orchestration plugin.
- Type: string
- Default value: select,update,insert,delete,show,create,describe,begin,if,end,not,exists
- mid.property.jms.command.allowed_factory_names
- Comma delimited list of Java Messaging Service (JMS) connection factories that the MID
Server requires for a custom JMS activity or action. This property requires the
Orchestration plugin.
- Type: string
- Default value: connectionFactory, queueConnectionFactory, topicConnectionFactory
- mid.property.ssh.use_snc
- Enables the use of the SNCSSH client for Discovery and Orchestration. Change this
property to false to use J2SSH. This property applies to all MID
Servers connected to the instance.
- Type: true | false
- Default value: true
- mid.property.powershell.use_base64_password
- If the Credential is set to be specific to certain MID Servers, then the property can also be set to those same MID Servers. Leaving the MID Servers field empty will apply to all MID Servers.
- Type: true | false
- Default value: false
- mid.sa.prefer_powershell
- Enables MID Server to use PowerShell Remoting.注:It is not recommended to change this property as it is being deprecated.
- Type: True | False
- Default value: true
- mid.sa.ssh.use_sncssh
- Toggles SSH between non-interactive and interactive modes. True corresponds to
non-interactive mode and allows probes to open sessions with the device without waiting
for a prompt. False corresponds to interactive mode, which requires interactive sessions
with the device for network devices and servers.
- Type: True | False
- Default value: true
- mid.sa.windows.allowable_failures
-
Specifies the number of allowable failures before the MID Server stops executing the pattern. Once the limit is reached, the next failure will terminate the pattern. A failure occurs when a PowerShell command can't complete successfully due to issues such as authentication failure, command timeout, or command execution exceptions.
- Type: integer
- Default value: 2
- Values:
- 0: The first failure will terminate the pattern immediately.
- 1: The first failure is tolerated; the second failure will terminate the pattern.
- 2: Two failures are tolerated; the third failure will terminate the pattern.
- -1: no maximum limit on failures; the pattern continues regardless of the number of failures.
- mid.servicewatch.max_concurrent_connections
- Defines the maximum number of concurrent tasks sent to an individual host by a single
MID Server.
- Type: integer
- Default value: 7
- mid.shazzam.regulator.interval_ms
- Sets the interval, in milliseconds, in which Shazzam can launch packets.
- Type: integer
- Default value: 1
- mid.shazzam.regulator.packets_per_interval
- Sets the number of packets that
Shazzam
can launch in the time interval specified by the mid.shazzam.regulator.interval_ms
property.
- Type: integer
- Default value: 1
- mid.shazzam.threads
- Specifies the number of concurrent threads that Shazzam uses. Setting this or the
mid.shazzam.max_scanners_per_thread parameter to 0 disables Shazzam multi-thread
optimization.
- Type: Integer
- Default value: 5
- mid.shazzam.max_scanners_per_thread
- Specifies the number of concurrent scanners processed by each Shazzam thread. Setting
this or the mid.shazzam.threads parameter to 0 disables Shazzam optimization.
- Type: Integer
- Default value: 100
- mid.sm.discolog.max_log_size
- Limits the length of the log statements in the Horizontal Discovery Log. If the
results are truncated, the Command results reports, "Result is
larger than [value] characters and was truncated by the logger."
- Type: integer (characters)
- Default value: 1000
- mid.sm.discolog.max_object_size
- Limits the length of the object in the Horizontal Discovery Log. Objects in the log
statement are truncated to the number of characters set by this property's value. This
property only affects the object character size in the Horizontal Discovery Log. The
following message appears if an object is limited by this property "The max object size
reached the maximum limit of [value]. To adjust this use the mid property
mid.sm.discolog.max_object_size."
- Type: integer (characters)
- Default value: 5000
- mid.snmp.use_getbulk
- Specifies whether to use GETBULK to receive a large amount of data in batches. This
can be used to globally configure all MID servers.
- Type: true | false
- Default value: true
GETBULK can also be set at the probe level or for an individual MID Server. Settings are listed in the order of precedence:- SNMP probe parameter
- MID Server configuration parameter
- MID Server properties

- shazzam.chunk_size
- Maximum number of IP addresses Shazzam can scan in parallel. This property primarily
controls outbound port consumption.
- Type: integer
- Default value: 100
- mid.use_net_tools
- Enables or disables the use of net-tools commands during discovery of devices running
on the Linux operating system. Starting from Quebec, ITOM Visibility supports the iproute2 commands for discovery. By default,
ITOM Visibility and discovery patterns first use net-tools commands,
and only then, as a fallback, may use iproute2 commands. If all Linux-based devices and
applications in your IT network use iproute2 commands, disable net-tools commands to
make the discovery process more efficient.
- Type: true | false
