[mrtg] Graphing DNS queries - gauge or not??

[Petr Lázňovský]

Hi all,

I am try to graph nomber of DNS queries of Win32 DNS service. I run perl script which read A/CNAME and PRT records and push those two values into mrtg. Values are increment counters, all new DNS queries are added to existing number. I expect the increment counter should be handled similar as SNMP byte/packet count from iface. By this reason,  I let out the GAUGE option in .cfg file. But in this case, no values going into graph anywise the external script pushing values into mrtg  ok (verified by --debug option), in .log file, there are still only actual value in very top line. Every logrotate ir overwiten by new value.

When I include GAUGE option in .cfg file, then graphs is filled by vallues, but only incrementing sum.

What I am doing wrong???
