mrtg/rrd not functioning for switch

[unkefers]

I have a new nagios XI install. When I configure the switch it finds all the ports just fine. However, when it checks the bandwidth monitor for the port it gets an error unknown and "/var/lib/mrtg/swithname_151126121.rrd does not exist." When I check the server it created the file "-rw-r--r-- 1 root root 105164 May 11 08:25 switchname_151126121.rrd" What am I missing.

I've noticed RRD failing with a similar error the first time, and then being okay the second time the service was checked. Might that be the case for you? (I suspect the file is created shortly after the error is thrown, not in time to work for the first check.)

I found my problem. It equated to a type caps vs. lowercase. Thanks for the reply
