XorMon, open source under GPL v3, monitors Cohesity DataProtect as storage and as backup. It obtains data via REST API from the XorMon host to Cohesity's nodes, and graphs capacity, IO, data and latency per pool and per cluster, IO, data, CPU, latency and memory per node, drive and port statistics, and health status.

Which Cohesity DataProtect metrics does XorMon show in its UI?

XorMon shows Cohesity DataProtect pools with capacity, IO, data and latency, drives with IO, data, latency and utilization, ports with data, packets and errors, nodes with IO, data, CPU, latency and memory, and the cluster with IO, data, latency and capacity.

The feature matrix has a Cohesity tab in its storage section and in its backup section, with the same DataProtect metrics, health status, and performance and hardware event alerting. In XorMon, event alerting sends an alert when a device turns red in the global health status dashboard, and a clear alert when it turns green again.

How does XorMon connect to Cohesity nodes, and on which port?

XorMon obtains data from Cohesity via REST API, with access from the XorMon host to Cohesity's nodes on port 443.

The XorMon deployment table lists Cohesity DataProtect with REST API as the interface and port 443.

Key points

• Monitors Cohesity DataProtect via REST API, from the XorMon host to Cohesity's nodes.
• Listed under both storage and backup monitoring; the installation sits under the storage section.
• Pool and cluster: capacity, IO, data and latency; node: IO, data, CPU, latency and memory.
• Drive: IO, data, latency and utilization; port: data, packets and errors.
• Health status, performance and hardware event alerts, open source license (GPL v3).

Installation and configuration for Cohesity DataProtect

Data is obtained from Cohesity via REST API.

• Allow access from the XorMon host to Cohesity’s nodes on port 443
  
  
• Create a new user with the Viewer role on the storage
  • Login to Cohesity GUI
  • Go to Settings -> Access management
  • Add Local User and assign “Viewer” (example uses 'stor2rrd' user but use 'xormon' preferable)
    
• Add storage device to configuration in the UI:
  XorMon UI ➡ Settings icon ➡ Device ➡ Storage ➡ New ➡ Vendor:device ➡ Cohesity : Cohesity DataProtect
  
  
  Use Cohesity Cluster loadbalancing FQDN in the device configuration
  
  
• Run "Test" for configured storage device, it must show "OK"
  
  
• Wait about 1 hour, then reload the web browser, you should see it in XorMon UI
