Splunk website monitoring Thread limit reached

[Ramesh_Euddham]

Hello all,

We have encountered a performance issue with our website monitoring inputs. It appears that the thread limit reached, causing multiple input executions to be skipped. This led to a significant load on our server, and eventually, the website monitoring app stopped functioning.

This is happening frequently  and restarting Splunk isn't helping. 

If anyone has experienced similar issues or has suggestions on how to manage thread limits more effectively  your input would be greatly appreciated

Hi @Ramesh_Euddham 

Under the Configuration page/tab for the Website Monitoring app, what do you have under Thread Limit? 

It sounds like you have more website checks configured than the amount of threads and the add-on is skipping some of your checks. Consider increasing this limit to see if this resolves the issue.

The relevant code for this is at https://raw.githubusercontent.com/LukeMurphey/splunk-website-monitoring/442d08de5bbfed4a879de3b537ea...
