Agent Client Collector Monitoring provides various default checks and policies.

## Provided checks {#agent-policies-checks__section_xtp_tf1_ckb}

The following tables list the default checks. You can edit these checks as needed. For more
information about a specific check, see its Check Definitions page, as described in [Checks and policies](https://www.servicenow.com/docs/F0COo~NAOjYK~CKffe4bKA "A check is a combination of a command and its configuration. The check is executed on the Agent Client Collector's devices to gather data from those devices.").

| Basic Discovery | Runs basic ServiceNow Discovery on all agents, every 12 hours. This check extracts basic information about the host and its running processes. The host information is used to create the corresponding host in the CMDB, while the running processes create the classified application CIs. You need advanced OS privileges to use the Net stat command to discover ports. The command that you run depends on your OS, as follows: * Linux: `sudo -n netstat -antp` * Windows: `netstat -anop TCP` {#agent-policies-checks__ul_uyb_djq_jkb} | check-discovery-basic |
