[mrtg] Re: default (not gauge) no updating

[Koelstra, J. (Jan)]

Mike,

Since the .logfile gets updated with each poll I think you don't use rrdtool.
But that is not the problem.
Your counters increase only with a small amount per poll.
By default MRTG calculates the rate per second. With a 5 minute poll cycle a counter that increases less than 300 will have a rate of less than 1 per second....
You can try the "perminute" or even "perhour" option to get a graph.

HTH,

jan

Subject: [mrtg] default (not gauge) no updating


All,

I am trying to configure MRTG (2.14.7) using rrdtool (1.2.12).  All of the gauge graphs are working great, but one that is supposed to use the default "counter" method never updates.  The gauge option missing is the only difference for this one graph, and if I put the option in, then the graph updates and works (although the data is obviously wrong, since the value read via SNMP is a counter).

Every time MRTG runs, the values are polled correctly.  Since all of the values are read from the same device, and this graph works ok when using gauge option, this does not seem like a lifetime/timestamp problem.  The problem is that with every update, the new counter values are just pushed up to the latest timestamp, and all the old values are set to zero.

An example (just first few lines of the .log file):
1163279100 63966 30760
1163279100 0 0 0 0
1163278801 0 0 0 0
1163278800 0 0 0 0
1163278500 0 0 0 0
1163278200 0 0 0 0
1163277900 0 0 0 0
1163277600 0 0 0 0
1163277300 0 0 0 0

and a bit later:
1163280001 64007 30763
1163280001 0 0 0 0
1163279701 0 0 0 0
1163279700 0 0 0 0
1163279400 0 0 0 0
1163279100 0 0 0 0
1163278800 0 0 0 0
1163278500 0 0 0 0
1163278200 0 0 0 0
1163277900 0 0 0 0

later still:
1163280301 64026 30764
1163280301 0 0 0 0
1163280001 0 0 0 0
1163280000 0 0 0 0
1163279700 0 0 0 0
1163279400 0 0 0 0
1163279100 0 0 0 0
1163278800 0 0 0 0
1163278500 0 0 0 0
1163278200 0 0 0 0

Thanks in advance for any suggestions or hints.
