Hi All
I am using Nagios with PNP4nagios as a graphing addon. I was using the
synchronous mode of PNP operation where in for every data collected the
process_perfdata is run and the data gets stored in the database. My
polling was such that for few services like CPU and bandwidth usage the
frequency of polling was done every 20 secs. This added a lot of load on
my nagios server box. Its CPU was constantly working at 70-75% and hence
i decided to switch over to Bulk with NPCD mode and followed all the
instructions given in the PNP4 site. Everything went fine and nagios
also verified the configurations correctly. But while starting the
nagios service i got the following error message as shown below.
Can someone tell me what was the reason for it and is there anything
that i should be concerned. Please let me know.
Note: After starting the nagios server again i am seeing the data being
collected and shown in the graphs. No issues in this regard. Now the
load on my nagios server is significantly reduced. I could see that the
CPU usage has come down from 70-75% to 40%.
