Measures reported by BackupProcessTest
Application processes
can be identified based on specific regular expression patterns. For
example, web server processes can be identified by the pattern *httpd*,
while DNS server processes can be specified by the pattern *named*.
For each such pattern, the BackupProcessTest reports a variety of CPU and memory
statistics. The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Num_procs_running |
Number of
instances of a process(es) currently executing on a host. |
Number
|
This value
indicates if too many or too few processes corresponding to an
application are executing on the host. |
| Cpu_util |
Percentage of CPU
used by executing process(es) corresponding to the pattern specified. |
Percent
|
A very high value
could indicate that processes corresponding to the specified pattern
are consuming excessive CPU resources. |
| Memory_util |
For one or more
processes corresponding to a specified set of patterns, this value
represents the ratio of the resident set size of the processes to the
physical memory of the host system, expressed as a percentage. |
Percent |
A sudden increase
in memory utilization for a process(es) may be indicative of memory
leaks in the application. |
