Removing RRDtool Spikes¶
You might have come upon some "spikes" in your graphs. These are perfectly normal and happend due to machines that have rebooted and have reset their counters or poller timing issues or other anomalies that might occur.
There is a script called
removespikes.pl made specially to fix these cases. You can find it in the
scripts/ folder of your Observium installation.
Type something in the command line like the following:
for i in rrd/*/*.rrd; do scripts/removespikes.pl $i; done;
You should probably see some messages like these:
