Dashboard is running extremely slow.

Hi team, 

I have created a dashboard with 8 panels, but it is running extremely extremely slow. how to improve the performance?

Here is the XML source:

@gcusello , thank you for the solutions. I am investigating.

Hi @cheriemilk,

good for you.

Ciao and happy splunking.

Hi @cheriemilk,

you have to use Post process Search  (https://docs.splunk.com/Documentation/Splunk/8.1.0/Viz/Savedsearches#Post-process_searches_2) to have only one search to run iin the dashboard to specialize for each panel.

Try the below modification of your dashboard:

<form>

      </default>
    </input>
    <input type="dropdown" token="DC">

 If one panel doesn't run, please check the fields in the base search, you must have all the fields in the following panels in the base search.

For more infos about using of Post Process Searces, see the Splunk Dashboard Examples App (https://splunkbase.splunk.com/app/1603/).

Hi @gcusello ,

Thanks for the suggestion. I tried and the performance does improve. But why the progress bar for query in each panel looks like always in "in progress" status after 1 or 2 hours, and never ended (please refer to the attached screenshot below.) The time range I select is 'Last 24h.

Is there any other option I can use to speed up the dashboard running?

[gcusello]

Hi @cheriemilk,

probably you have very many events to read every time during searches.

The only way to have best performaces is to accelerate searches.

You can do this in different ways:

• if the searches in panels are always the same and doesn't take new logs every time (e.g.: yesterday or last month logs) you can schedule (in the night) a Report and embed the report in your dashboard;
• otherwise, if your data are continously indexed, you should schedule a search (e.g. every 5/10 minutes) that add results of the last period to a summary index, then you can use this index for your searches in the panels;
• third solutions is to use a Datamodel.

you can find more infos about search accelarations at:
