Hi Team,

I have created check_log plugin for monitoring alert, but the graph value is showing always the average value in graph. So i could not find the exact count of alert.

CLI output

Warning: 20 | datalost= 20

Graph should show value 20, but it is showing the average value

Please find the attached screenshot.

Thanks,

Attached the complete screenshot

Hello @mejokj

Nagis XI uses RRDs (round robin database) files to store time-series performance data and limit storage requirements. The size of each rrd file remains the same over time and this is accomplished by using consolidation functions ( average, min, max) for primary data points. This is necessary as large XI systems will have thousands of host and services requiring performance graphs.

If you hover over the graph for the most recent data point, it should be close to the actual plugin value, but there will be some difference.
