Visualizing PCP system performance data in Grafana on RHEL-10 using Valkey

Environment

• Red Hat Enterprise Linux 10
• Performance Co-Pilot(PCP)
• Grafana
• Valkey

Issue

• How to plot the system performance data captured by PCP (Performance Co-Pilot) in Grafana using Valkey in RHEL-10 ?
• How to monitor the system performance graphically in RHEL-10?
• How to monitor the historical or live PCP performance data in Grafana ?

Resolution

1. Install PCP, grafana and valkey

# dnf install pcp-zeroconf grafana valkey

2. Start and enable the required services

# systemctl start pmcd pmlogger grafana-server pmproxy valkey
# systemctl enable pmcd pmlogger grafana-server pmproxy valkey

Once the services are started access the Grafana web UI from Content from localhost is not included.Content from localhost is not included.http://localhost:3000/.

• Replace localhost with your machine IP to access Grafana web UI from a remote machine.

Enter the default username and password as admin. Choose skip to continue default password or change it as per your requirement.

3. Enable PCP Plugin

• From menu (three horizontal lines) choose Administration -> Plugins and data -> Plugins
• Search and Enable Performance Co-Pilot Plugin.
  • Else you can also open Content from localhost is not included.Performance Co-Pilot plugin page directly.

• Add data source from Connections -> Data sources
  • Or directly open the Content from localhost is not included.Data Source Page link.

• Search and select PCP Valkey
• Enter the http://localhost:44322 URL under HTTP and click Save & test
• You can add other PCP data sources as well such as PCP bpftrace and PCP Vector to visualise different metrics.

• Open the Dashboards tab under Valkey datasource and Import PCP Valkey: Host Overview

• Goto Home -> Dashboards and click on PCP Valkey: Host Overview
