Re: [Nagios-users] Nagios monitoring limits: hosts and services
I'm starting to get complaints from our Operations group that the Nagios web GUI is getting slow. This is on a version 1.x Nagios server. The server is monitoring 678 hosts and 3481 services organized in 29 host groups. Most checks are done on 5 minutes intervals. I've gone over all of the documented tweaks to improve performance. The hardware seems adequate and isn't starved for CPU; loads seem reasonable; although the Check Latency under the Performance Info screen continually creeps up - currently at Max. 23 seconds. Time to load the Status Overview screen: 8,5,6,6 seconds Time to load the Status Summary screen: 42,35 I guess my first question is what do your uses expect in terms of performance? Am I missing the boat on something real basic here? How many hosts/services do you manage per Nagios host? Those times seem long for that number of hosts. In most cases (including a system I'm looking at now with around 2100 hosts and 11,000 services being monitored) the bottleneck's bandwidth more than the server on the big pages like the service detail, but I haven't used a Nagios 1.x system for quite some time. Have you tried keeping your status data in RAM? I've seen some pretty decent performance gains from doing that in other cases. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

This is not unusual for a 1.x installation with large numbers of hosts/services. I had hostgroup overview pages that were taking up to 5 minutes to generate and I needed to cron them. There were significant optimizations done in 2.x to correct the way the CGI's internally traversed host and service entries resulting in the same pages generating in about 6 _seconds_. You should upgrade. 1.x is getting very old now. -- Marc - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
