Slow views
| Note |
|---|
This option is only available in Checkmk 2.2 or greater. |
Some built-in or own views may take longer time than expected. In order to detect slow views, you have to set:
The log level to DEBUG at Setup > General > Global settings > User interface > Log levels > Slow views
A threshold (in seconds) at Setup > General > Global settings > User interface > Threshold for slow views
The logging is disabled by default. The default threshold is set to 60 seconds.
...
If enabled, one log entry per view rendering that exceeds the configured threshold is logged to var/log/web.log.
A slow-view log entry will look like the following:
