((1) This aspect is realized either as a server-side component or by a 'customized' agent.
...
(5) A single value cannot be entered due development of logically-independent modules by different community groups.
[^]: Runtime analysis process and considerations:
- Isolate the CPUs on the monitoring node. [ Add isolcpus option in the grub. CPU0]
- Run the agent on the isolated CPU (CPU0). [ Use taskset command to run agent-processes with appropriate CPU-mask: 0x01]
- Plugins: Configure agent to monitor following metrics - CPU, Memory, Disk, Interface, IPMI, processes, libvirt, Caches, OVS, hugepages.
- Output: Make agent to send metrics over network (Ex: influxdb running on separate node)
- Workload: stress-ng + iperf.
- Monitoring duration: 5 minutes.
- Frequency: 1sec.
- Collect Metrics (using any other tool) to analyze agent's runtime performance [ Ex: Used Snap to collect ‘collectd-process’ metrics and CPU and memory data]
- Note the iperf performance ( to study any effect on it due to collectd]
