Wrong alert with swap file
Re: Wrong alert with swap file
Hello and welcome to the forums!
The check_swap plugin acts a little differently from most plugins. The warning and critical thresholds represent the percentage of available swap, not the percentage of used swap.
The warning level means it's a warning state if less than that amount of swap is available. E.g. If it's set to "20%", then it's a warning state when more than 80% of the swap is being used.
This is also the reason why the warning threshold is typically always higher than the critical level.
The reason you're getting a critical alert is because your system's percentage free (67%) is lower than 90%, so it's in the critical range. The way you have it configured, if you use more than 10% of the swap, it's in the critical range.
Possible solution
If you're trying to configure your plugin to trigger warning if more than 90% is used, and critical if more than 95% is used, then use this configuration.
