While monitoring your Citrix Virtual Apps and Desktops or VMware Horizon environment(s), Goliath collects many metrics. Depending on your environments density/configuration, this can be an intensive process and we have seen some customer environments that are not able to handle the load. The collection process can be modified improve agent performance/load on the affected machines.
Refer to the steps below for instructions on adjusting the collection. Please note, the below steps are only applicable for Goliath Agents running v11.8.0 and newer.
Adjusting Agent Metric Collection
- RDP to the Goliath Server
- Open Windows File Explorer and Navigate to the Bin folder within the Goliath Server install directory.
- The default location is either C:\Program Files (x86)\MonitorIT\Bin or C:\Program Files\MonitorIT\Bin depending on your Goliath version
- Sort the folder by File Name in ascending order, at the top you will see a file named AgentCollectionRates.txt double click to open the file.
- Once the file is opened, you will see a list of the metric collection items and their corresponding rates, defined in seconds.
- Update the applicable rate(s). Once ready, save and close the file.
- See the below sections for Metric Collection Rates Overview and Collection Recommendations for additional details on the metrics and potential rate changes.
- To disable a metric from being collected, enter a rate of 2147483647
- The updated collection rate(s) will now be applied the Goliath Agents within 60 seconds.
