<p>Hi List,</p>
<p>Using the disk check we can see the usage and set thresholds.<br />The performance info is stored into a RRD and viewed through pnp.</p>
<p>This all works as expected.</p>
<p>Now that the RRD contains historical data, I was wondering if there are any checks or systems available which can detect and and alert on suspicious trends.</p>
<p>For example in the case of a disk check.<br />If the disk usage increased with 50% over the last 15 minutes, that indicates a problem... while this doesn't necessarely mean a threshold is exceeded.<br />Or if the disk usage is growing steady, we will run out of space in 2 days, ... but the coninuous gentle growth indicates a problem (log file appends for example)</p>
<p> </p>
<p>Thanks for the info.<br /></p>
