Graph containing AVG value, improper graph. need a bar type

[mejokj]

Hi Team,

I want to generate one specific graph in nagios in bar graph format? is it possible for a single graph?

For example: Below graph showing some avg value, due to this I am not getting a proper graph like bar graph format.

Thanks

Hello,

Can you post a larger image of the screenshot, as I'm having trouble seeing any details. Thanks.

Also, to clarify, you'd like a Bar Chart for performance graphs? Is this correct.

-----> Yes, Bar Chart

Thanks

Hello @mejokj,

Currently, the best workaround for creating bar charts from performance graphs would be to click the hamburger menu in the upper right and download the data (csv,json or xml), and use another application such as Excel.

Hi Team,

Hello,

The time series performance graphs in Nagios XI are created from RRD 's (Round Robin Database) to save space. The size of each rrd file remains the same over time and this is accomplished by using consolidation functions ( average, min, max) for primary data points. This is necessary as large XI systems will have thousands of host and services requiring performance graphs.

The fact that you are getting average value is a feature of RRD's. If you would like more information, please see the following page:

Hello Benjaminsmith,

Thanks for your reply!!

I understood the point which you have mentioned.

Is there any chance to avoid these options only for single performance graph?

As my requirement will fulfill if the graph value remains an integer instead of decimal.

Thanks

Hello @mejokj,

The RRD configuration files is located in /usr/local/nagios/etc/pnp/rra.cfg, and defines the number of data entries per time period. Basically, the resolution is highest for recent data and lower for the oldest, again to save space.

You can up resolution but you will lose existing historical data, and it will require more space and processing power. The change will apply to all RRD graphs on your server.

We are planning to add more flexibility to performance graphs in Nagios XI 6.

Also, if you do make any changes, please backup your system.
