Nagios Support Forum

Hello,

We are currently evaluating NagiosXI. It is currently in trial mode. Our requirement is to generate performance graphs for CPU & Memory usage for all hosts eveyr week. When i click on REPORTS >> LEGACY REPORTS , i find that this feature is generating HISTOGRAMS and not the actual graphs which we want. Also there is no option to save it as a pdf and to email a parituclar group.

Secondly, when i click on HOME >> PERFORMANCE graphS >> HOST graphS >>, i am able to view the graph of every host & its corresponding service ( CPU, memory) individually . But there is no option to generate CPU or MEMORY usage graphs for more multiple hosts . Also there is no option to email this performance graph out as a report.

I dont want to send out those bland histograms to our customer. Is there any way to generate a pdf with different performance graphs for multiple hosts & schedule it to be emailed to a group in NAGIOSXI ?

Currently we don't offer this functionality in Nagios XI, however you may try using our graph Explorer component, which can give you at least some of this functionality. You can find our more about it here:

Also, we are working on a new feature in Nagios XI, called "Scheduled Reporting in Nagios XI". Please, check it out here:

Hope this helps!

I created a dashboard using graphs from the graph Explorer. Unfortunately the data on the dashboard never updates. Did I miss a setting somewhere? Is there a way to make the graphs update?

When adding a graph Explorer graph, when you "dashify" it, make sure you're using either the default time setting (which is "today"), or a setting like -7d, -48h, or something that subtracts from the current time. If you specify a specific start and end date you'll always get that particular set of data.

I used the setting -30d.

I created the graphs on 10/5 and there is no data for 10/6 showing (it stops about the time the graphs were made) when you load the dsahboard page.

Just out of curiosity, when you view the graph normally, does that data seem to show up ok?

If so I'll double check and make sure that data fetch is still working correctly...

The data appears to stop on the graph page as well....

IT act's the the CPU usage value has stopped reporting....

Try running from the command-line:

The restart didn't change the problem.

One of my co-workers was attempting to install a reporting service (pnp4nagios) and it's possible that he damaged the config file so the stats are no longer being collected. I'm exploring that angle now. Any tips would be welcome!

Ah, then it might be worth mentioning that pnp4nagios already ships with Nagios XI? ; ) It's the daemon running under the hood that processes all performance data. How fresh is this installation? If it's fairly new, it might be quicker to reinstall than to attempt to debug. However, if you've got a lot of hours into setting it up already and you'd prefer not to reinstall, we can take a look at what was changed with the 2nd installation of PNP.

You can access PNP's front-end at http://<yourserver>/nagios/pnp on a default Nagios XI install.
