process-exporter Query details

1. process cpu utilization

sum(irate(namedprocess_namegroup_cpu_seconds_total{
    instance="zunshang"}[5m])) by (groupname) * 100 / 4

namedprocess_namegroup_cpu_seconds_total{instance=“zunshang”}: All processes in the bottler server use cpu Time for (system、user)
irate(namedprocess_namegroup_cpu_seconds_total{instance=“zunshang”}[5m]): 5 Of the two nearest data points of each time series in minutes cpu Usage time rate
sum(irate(namedprocess_namegroup_cpu_seconds_total{instance=“zunshang”}[5m])) by (groupname)： Statistics of all processes system And user Use your time With groupname distinguish Process
4 ： Express cpu The number of cores sum(irate(node_cpu_seconds_total{instance=“zunshang”}[5m])) About equal to 4

2. The number of all threads produced by the server application

sum(namedprocess_namegroup_num_procs{
    instance="zunshang"}) by (groupname)

3. Process memory usage (PSS)

sum(namedprocess_namegroup_memory_bytes{
    instance="zunshang",memtype="proportionalResident"}) by (groupname) / 33020436480 * 100

33020436480 : The maximum memory byte size of the server
proportionalResident： PSS be relative to RSS The shared library memory size is calculated proportionally .N Process sharing , This library pair PSS The contribution of size is only 1/N

4. Server process memory usage (VIRT)

sum(namedprocess_namegroup_memory_bytes{
    instance="zunshang",memtype="virtual"}) by (groupname) / 33020436480 * 100
