Extremely High Load

I just sent 2 separate pm's to you with the system profile updated as well as the config for a broken system graph.

For your disk check issue it's because the amount of datasources changed, this is the error:

RRDs::update ERROR /usr/local/nagios/share/perfdata/XXXXXX/Drive_Usage.rrd: expected 22 data source readings (got 21) from 1544627995

You can either delete the RRD file in /usr/local/nagios/share/perfdata/HOSTNAME for that service and have it be rebuilt OR you can manually remove the extra data source:

Is there a difference in approaches? It seemed easier to just delete the files but that is not solving the issue. For example, we have a host with 4 drives. I deleted the RRD file for that check, let mrtg run over the span of 15 minutes, and it's still not showing any data. If I use rrdtool info it's showing:

ds[1].last_ds = "U"
ds[2].last_ds = "U"
ds[3].last_ds = "U"
ds[4].last_ds = "U"
ds[5].last_ds = "U"
ds[6].last_ds = "U"
ds[7].last_ds = "U"

Notice there are 7 in there and I know we only have 4 drives in the check. Is there maybe something I'm missing?

Forget it - took a lot longer - about 35-40 minutes or so but now it's reporting again. Thanks for your help. I'm going to do the same to the rest that are broken.

Glad to hear you got it working albeit taking a bit longer than expected
