Discovery log is too large and could not be saved

[Leo34]

Hi,

we have repeated errors in the log about a horizontal discovery pattern failing for some IPs.

However when trying to open the pattern log, it shows the message "Discovery log is too large and could not be saved".

Is there a property to increase the maximum size for pattern logs (temporarily)?

I found another question about this topic (https://community.servicenow.com/community?id=community_question&sys_id=e1a97a0fdb4773400be6a345ca96194b) but no useful answer.

The pattern in question is the original "Linux Server" pattern that comes with ServiceNow.

Thank you

Hi,

it turned out this is actually a bug.

Support came back with this answer:

This is a known issue on the Java code and has been fixed in New York Patch 3, Orlando, and now is ready to be tested on Madrid Patch 9. If a discovery pattern log exceeds the default size value of 4096000. The discovery pattern log will not be saved and the discovery log will have the following message: "Discovery log is too large and could not be saved"

Yes that default value is the size for "log" column under table "sa_discovery_log". Did you try to increase?

Is there any way to change the default pattern log size
