This sort of situation (irregularly arriving events) is not really suitable for RRDTool, which is optimised and designed for storing and graphing time sequence rate-based data, coming in at regular intervals.
One possibility would be for you to store your logs in a separate location, then your RRD gathering process could run regularly via a scheduler every 5 min, and count the new logs since its last run. This would be an 'absolute' type counter giving you a stored value in logs/sec that you could process as sum(interval*value) to get total number of logs. Getting logs from time previous to the last update would not work - youd have to discard these. If this is unacceptable, then you need to look at another more heavyweight and flexible database - maybe mysql or postgres...

When I receive a logline, I would like to flush this to rrdcached immediately, but for this to work I need to be able to not set a absolute value, or a counter, but a increment current value (in timestamp range) by 1. Is this possible? If not I would need to keep track of my own counters in for example redis, incrementing here, and flushing to rrdcached.. which would not be nessesary if rrd can do the incrementing. And what about when I receive some loglines from a day back (because of some network failure)? -- View this message in context: http://rrd-mailinglists.937164.n2.nabble.com/Incrementing-type-tp7581036p7581041.html Sent from the RRDtool Users Mailinglist mailing list archive at Nabble.com. _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
