Re: [Nagios-users] cpu usage / memory usage
Hi Hugo, Thanks for the reply. I need to handle both CPU usage and Memory usage. i) I think check_load plugin supports cpu usage which provides the load information using with: uptime command. If we need cpu usage with vmstat command which plugin do I need to use. ii) How to handle memory usage, which plugin do I need to use. Correct me if am wrong with this understanding. Thanks, Raghavendra. Can some one provide directions how to handle cpu usage / memory usage. I am using check_disk plugin for disk usage. Assuming you're talking about a unix variant, check_load is included in the standard plugins and can be used to infer cpu usage. There are also quite a few cpu and memory specific plugins available at http://www.nagiosexchange.org. Correct me if I am wrong but the load on a unix system is not quite nescessary related to the CPU usage. You can get the load info for example with: uptime 19:24:23 up 165 days, 1:09, 3 users, load average: 0.02, 0.02, 0.00 And your CPU usage with: vmstat procs ---memory-- ---swap-- -io --system-- cpu r b swpd free buff cache si sobibo incs us sy id wa 0 0 1072 67176 184720 79293600 076 1138 110 0 0 100 0 While there usually is a relation between the two of them they are two different things. The question is which of these two do you (raghavendra kristam) want? There is a check_load plugin that does the load thing. For most alerting purposes that is quite enough. As th load tends to go up if you are low on memory. Hugo. - Using Tomcat but need to do more? Need to support web services, security?

Hi, After Installed Nagios2.7 and Nagios plugin-1.4.5. The following configuration files are located in /usr/local/nagios/etc cgi.cfg-sample commands.cfg-sample localhost.cfg-sample nagios.cfg-sample resource.cfg-sample Later copy those from $NAGIOSHOME/etc/*.cfg-sample to $NAGIOSHOME/etc/*.cfg as cgi.cfg commands.cfg htpasswd.users localhost.cfg nagios.cfg resource.cfg The below configuration are not availble in /usr/local/nagios/etc/ . Do we need to create these files in /usr/local/nagios/etc/ or did I missed any thing during installation time.

But, it may be even better. For instance, your Java app will throw out of memory errors if it reaches the maximum allocated to the VM. This is usually way below the amount available to the OS. So, you'll want to measure memory usage via JMX and not via the standard OS calls. -Dave David Rudder wrote: c) is a difficult one, but I expect it's been handled before. Tomcat stores its logs in the httpd common log format. So, any nagios plugins that examine the Apache logs should be able to handle Tomcat's as well. I see Ethan wrote a check_log that will check for a pattern. Maybe you could build on that. If you're just looking to see if a request took a long time, you can add %D to the access log pattern (specified in conf/server.xml). That shows the time it took, in millis, to fulfill the request. However, I'm not sure if a page's request takes longer for a client with a slow link. Anyway, given the standardized way Tomcat stores it's log, it might not be too difficult to find someone who solved the same problem for Apache's httpd and apply that to Tomcat. -Dave raghavendra kristam wrote: Hi, I am quite new to nagios and finally I installed the required softwares on linux machine.
