I'm confused, earlier you showed this file existed
http://support.nagios.com/forum/viewtop ... 439#p34284

and now it doesn't...

Did you delete it?

[kotterbein]

no, I took no action other than the commands as stated... this is why I cannot figure out why this continues to flap- one poll it is there, the next it is not.

[kotterbein]

looks like the noted device has been removed- perhaps overnight by our NOPS group... I re-ran using an rrd file that was there:

Your command it wrong you have some extra info in the path

Run

Code: Select all

/usr/local/nagios/libexec/check_rrdtraf -vv -f /var/lib/mrtg/6.0.2.251_59.rrd -w 1000,2000 -c 2000,3000

instead of

Code: Select all

/usr/local/nagios/libexec/check_rrdtraf -vv -f /var/lib/mrtg/var/lib/mrtg/6.0.2.251_59.rrd -w 1000,2000 -c 2000,3000

So that looks like it should be working ok

Are you seeing errors in the Web UI?

[kotterbein]

yes- it's random...

I may have to just blow it all away and do a re-install I suppose, but I cannot possibly understand why this would be taking place:

[scottwilkerson]

I guess the biggest thing to look at when you see this, is does this file exist
/var/lib/mrtg/6.0.-.---_222.rrd

[kotterbein]

they do... is there some sort of timing issue perhaps between the check and the creation of the file?
