Set the maximum number of entries in the error log.


[config]    errlog=n

n is an integer in the range 10—10,000. The default value is 500.


errlog is the maximum number of entries in the InterSystems IRIS® data platform system error log (see InterSystems IRIS System Error Log for more information). The log file expires old entries as this limit is reached.

Changing This Parameter

On the Advanced Memory page of the Management Portal (System Administration > Configuration > Additional Settings > Advanced Memory), in the errlog row, select Edit. Enter a number of entries.

Instead of using the Management Portal, you can change errlog in the Config.configOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in Editing the Active CPF).
