Monitoring Zerto Virtual Replication : Zerto Performance Counters
  
Zerto Performance Counters
During installation of Zerto Virtual Replication, Zerto-related performance counters are added to the Windows Performance Monitor on the machine where the Zerto Virtual Manager runs.
Uninstalling Zerto Virtual Replication, uninstalls the Zerto-related performance counters. Upgrading Zerto Virtual Replication updates any changes to the Zerto-related performance counters.
The Zerto-related performance counters are collected on the protected site only. These counters are described as follows.
Zerto Checkpoints
Checkpoint failures in last 10 minutes
Number of checkpoints that failed to be inserted in last 10 minutes.
Checkpoint insertions in last 10 minutes
Number of checkpoints inserted in last 10 minutes.
The maximum is 120; normal performance is 90–115; less than 40 indicates a problem.
Time to insert last checkpoint
Time in milliseconds needed to insert the last checkpoint; normal is less than 5 seconds.
Zerto Connectivity
# of connected VRAs
Number of VRAs connected to the local Zerto Virtual Manager.
# of peer Zerto Virtual Managers (ZVMs)
Number of Zerto Virtual Managers connected to the local Zerto Virtual Manager.
Zerto GUI
Concurrent GUI calls to the ZVM
Number of concurrent GUI calls to the local Zerto Virtual Manager.
Zerto Reflections
AWS reflection collection time
Time in milliseconds needed to collect AWS environment data.
Hypervisor reflection collection time
Time in milliseconds needed to collect vCenter Server or SCVMM environment data.
vCenter Server collection time should be less than 10 minutes.
SCVMM collection time should be less than 25 minutes.
Reflection data pushed in last 10 minutes
Size in bytes of environment data pushed in last 10 minutes to Zerto Virtual Managers connected to this site.
Reflection data pushed to peer ZVMs
Size in bytes of last pushed environment data.
Reflection data received from peer ZVMs
Size in bytes of last received environment data.
Reflection data received in last 10 minutes
Size in bytes of environment data received in last 10 minutes from Zerto Virtual Managers connected to the local Zerto Virtual Manager.
Reflections pushed to peer ZVMs in last 10 minutes
Number of times environment data was pushed to peer Zerto Virtual Managers in the last 10 minutes.
Reflections received from peer ZVMs in last 10 minutes
Number of times environment data was received from peer Zerto Virtual Managers in the last 10 minutes.
Retained data
Size in bytes of total retained pushed or received data.
vCD reflection collection time
Time in milliseconds needed to collect vCD environment data.
Zerto Remote Calls
Active incoming remote calls
Current number of active incoming calls being processed.
Active outgoing remote calls
Current number of calls sent to WCF services for which the Zerto Virtual Manager is still waiting for a response.
Incoming remote calls in last minute
Number of incoming remote calls received in last minute.
Outgoing remote calls in last minute
Number of outgoing remote calls executed in last minute.
Zerto RPO
Average RPO
Average RPO in seconds for all VPGs, displayed in the Dashboard.
Current maximum RPO

Current minimum RPO
Current minimum RPO in seconds for all VPGs in this site.
Zerto System State
Number of alerts
Current number of active alerts.
System state loop length
Execution time of one system state loop.
This should be less than 40 milliseconds.
Time to calculate statistics
Time in milliseconds needed to calculate statistics during a system state loop.
Time to retrieve active alerts
Time in milliseconds needed to collect local Zerto Virtual Manager active alerts during a system state loop.
Time to save VRA performance counters
Time in milliseconds needed to save VRA performance information to a file.
Zerto Visual Query
Time to execute a VQ build loop
Time in milliseconds needed to execute a single VQ build loop. This should be less than 25 milliseconds.
Time to retrieve hypervisor information (reflection)
Time in milliseconds to execute a remote query on peer Zerto Virtual Managers to retrieve hypervisor information from remote sites.
Time to retrieve local VM list
Time in milliseconds needed to retrieve the list of virtual machines from the local hypervisor.
Time to retrieve local VPG data
Time in milliseconds needed to retrieve VPG data from the local Zerto Virtual Manager.
Time to retrieve VPG list
Time in milliseconds to execute a remote query on peer Zerto Virtual Managers to build a list of VPGs on remote sites.
Zerto VRA Counters
# of VRAs not updated
Should be zero or close to zero.
# of VRAs updated
Should be near or equal to the number of active VRAs.
Average time of 5 most time-consuming VRA updates
Should be close to the median VRA update time.
Median VRA update time
Median time in milliseconds of last 100 VRA updates.
