How often is the “Client CPU” metric is gathered in ControlUp Realtime DX?
Someone asked about the frequency of the "client CPU" metric and whether it is an average. It is updating at 3 seconds, and there could be a bigger interval for seeing it in solve (up to 10 seconds). However, users may be seeing different values in their local task manager, and @member or @member could provide more details on this. It is possible that the stress levels in the configuration are set to average so the values change less often.

Is PVS device write cache free disk space” still not available to use as a stress indicator in ControlUp
A user inquired if "PVS device write cache free disk space" was available as a stress indicator - it was not, though the Trigger Pack offered a different trigger. The user was looking for overall machine stress, but the individual value didn't roll up to the total.

ControlUP Monitoring: Combining CVAD Logon Times with FSLogix Integration without UPM? Supported Configuration?
A user asked about running FSLogix and UPM together without issues. It was suggested to not use Director for logon times as ControlUp is more accurate and to focus on the Windows logon time. It was also recommended to use the logon duration analysis script provided by ControlUp and establish a baseline. Additionally, FSLogix integration interrogates a remote file share every 5 minutes and does not provide free space info, other than that it can be requested via Solve UserVoice. Links provided: https://www.controlup.com/resources/blog/entry/analyzing-logon-duration-just-got-better/, https://www.controlup.com/script-library-posts/enable-requirements-for-logon-duration-analysis/.

How Can I Generate a Report for IOPS and/or Read/Write Latency for VMware Datastores?
A user asked how to get a report for iops and/or read/write latency for a VMware datastore. It was suggested to use the Host Trends report in ControlUp Insights/Solve or export schedules. A trigger with thresholds can also be used along with the exports or export-cuquery to indicate when the datastore is slow and report back. Host Stress showed latency of almost 1.3 sec. for read and writes.
