I would suggest you stagger your jobs over the 5 minutes interval instead of trying to do everything at exactly every 5 minutes. Try 0,5,10,15,20,25,30,35,40,45,50,55 * * * * do 1/5th of the job 1,6,11,16,21,26,31,36,41,46,51,56 2,7,12,17,22,27,32,37,42,47,51,57 3,8,13,18,23,28,33,38,43,48,53,58 4,9,14,19,24,29,34,39,44,49,54,59
Ensure your 1/5th job finishes with 1 minute 1250 RRDs - are you storing indiviudal DS in its own RRD. Say you collect ifInOctets, ifOutOctets for router1/router2/router3. You may be creating 6 RRDs where you can do with 3 in a logical way. Simply create router1.rrd with DS ifInOctets and ifOutOctets. This will definitely cut down the number of RRDs Simone Felici - Alpikom Spa wrote: > Hi to all! > > I've al little problem with my server, rrdtool and maybe snmp. > > My server is collecting informations and updating more or less 1250 rrd > files. > Most of these files are collecting traffic informations on routers via SNMP > and my custom scripts. > These scripts simply checks the uptime of the device and then get the > COUNTER32 values to update the rrd files. > > My problem is that my system crash one time every week.
