Performance Co-Pilot (PCP) on my RHEL server to capture performance logs
RHEL 7 (prior to RHEL 7.4)
PCP is included in the base RHEL and Fedora distributions. A minimal installation requires just the pcp package (and its dependencies) to enable performance data logs to be collected for later analysis:
yum install pcp
systemctl enable pmcd
systemctl enable pmlogger
systemctl start pmcd
systemctl start pmlogger
pcp
pmstat
pmatop
pmcollectl
At the moment Vector comes with the following list of widgets and dashboards that can be easily extended. Here is a short list of metrics available by default.
CPU
- Load Average
- Runnable
- CPU Utilization
- Per-CPU Utilization
- Context Switches
Memory
- Memory Utilization
- Page Faults
Disk
- Disk IOPS
- Disk Throughput
- Disk Utilization
- Disk Latency
Network
- Network Drops
- TCP Retransmits
- TCP Connections
- Network Throughput
- Network Packets
