Metrics

The tables below list the default set, and optional extended set, of system metrics collected by the SolarWinds Snap Agent.

Default Metrics

CPU Metrics

CPU Metric Tags

Disk Metrics

If you want to control for which disks metrics are gathered, you can use mount_points and exclude_disks setting. Add aosystem collector section with your custom settings to the main agent configuration file config.yaml:

1
2
3
4
5
6
7
8
...
collector:
  aosystem:
    all:
      mount_points: "*"
      exclude_disks: "/dev/loop*|/dev/sdb1"
...

or place an additional config section in task-aosystem.yaml:

1
2
3
4
5
6
7
8
9
10
11
12
13
...
workflow:
  collect:
    config:
      /system:
        mount_points: "*"
        exclude_disks: "/dev/loop*|/dev/sdb1"
    metrics:
      /system/cpu/guest: {}
      /system/cpu/idle: {}
      /system/cpu/interrup: {}
...

• The setting mount_points allows filtering mount points that will be monitored. The default behavior is to monitor only physical devices (ie. hard disks, USB, etc.). To enable monitoring of all devices, use ‘*’. You can also define a list of devices to be monitored by entering multiple paths separated with ‘|’, i.e. "/|/dev|/run".
• The setting exclude_disks allows to define which mount points should not be monitored. Multiple exclude patterns can be separated by ‘|’. Basic globbing patterns are also supported.

Timeout For Querying System Statistics

If you want to tune timeout used for collecting system statistics (i.e. disk metrics), you can use system_query_timeout setting. By default it is set to 20s. Add aosystem collector section with your custom settings to the main agent configuration file config.yaml:

1
2
3
4
5
6
7
...
collector:
  aosystem:
    all:
      system_query_timeout: "20s"
...

or place an additional config section in task-aosystem.yaml:

1
2
3
4
5
6
7
8
9
10
11
12
...
workflow:
  collect:
    config:
      /system:
        system_query_timeout: "20s"
    metrics:
      /system/cpu/guest: {}
      /system/cpu/idle: {}
      /system/cpu/interrup: {}
...
