As can be seen here in picture, appmon is showing a memory usage of 1877(187.7%) whereas threshold is 60(6%). I have gone through the entire documentation of appmon, but couldn't find any plausible reason. If someone has experienced this in past or have any idea about what this could be, please let me know. Thanks in advance.
Can you provide the details for the measure you're charting (the config screen as well as the details screen in the configuration)?
Also, I see this is tagged as 6.2. I would make sure you're on the most recent update of 6.2 but if this is a bug full support for 6.2 ended at the end of 2016 so support may be able assist somewhat but I doubt anything will be able to be fixed or looked at by development so I would try to upgrade to a supported version if and when possible.
