I'm using Nagios Core to monitor temperature of a walk-in freezer using Websesor EM08, which comes with its own Nagios plugin. Now Nagios Core covers my realtime monitoring and alerting just fine. However, I have the following requirements and I'm wondering what is the most suitable extension to use that will cover my requirements
1) Graphing. I need to be able to view a graph of the monitored temperature throughout the day
2) Reporting. I need to be able to generate weekly/monthly reports that can be sent to users
Any suggestions?

Re: Nagios Graphs and Historical Reporting
The easiest solution is to use NagiosXI, these features are built in.
Barring using XI, my preferred graphing solution is pnp4nagios.
Regarding reporting - some is built into core. What specifically are you trying to report on? Can you give us an example of data you might expect this report to contain?

Re: Nagios Graphs and Historical Reporting
many thanks for the quick reply. a reporting example would be: send a report containing the temperature of the freezer for last week, or last month. preferably a graph of the monitored temperature would be perfect, but I can live with a report of only temperatures and the time it was collected. something like:
_________________
|day | time | temp|
|sat | 12:00| 4.1 |
|sun | 12:05|5.0 |
etc
the only reason i'm using Nagios Core instead of Nagios XI is because I assumed that XI is the paid version, and I'm not looking to invest money on the monitoring solution yet
Thanks

Re: Nagios Graphs and Historical Reporting
pnp4nagios can generate CSV data for you:
http://docs.pnp4nagios.org/pnp-0.6/xport
You could have a cron job curl this data and E-mail it to you or do whatever else you like with it on whatever schedule you deem necessary. pnp4nagios can also generate PDFs that you can likewise E-mail to yourself or whatever.

Many thanks. I'll give it a go

Re: Nagios Graphs and Historical Reporting
The pnp4nagios wiki is a fine documentation source.
Re: Nagios Graphs and Historical Reporting
Just an update so this could be useful for anyone else
PNP4Nagios worked quite nice for what I'm looking for. I now have temperature alerts and performance graphs for the Websensor EM08. Sync mode with pnp4nagios 0.6.25 is apparently not supported with nagios core 4.1.1 (yet). but bulk mode worked perfectly
I haven't tried the export to csv feature yet. I'm waiting for more data to be generated before I test it.
Many thanks for the support

I've never seen it not. Let us know if it fails, otherwise I'll look forward to locking this topic and marking solved?
Re: Nagios Graphs and Historical Reporting
using the following URL at a browser gets the correct output
however using curl at the command line to download the content gets me an error
is something wrong with the curl command?
