PCSConfig - command `pcs config`¶

This module provides class PCSConfig for parsing output of pcs config command.

Typical /usr/sbin/pcs config output looks something like:

Cluster Name: cluster-1
Corosync Nodes:
 node-1 node-2
Pacemaker Nodes:
 node-1 node-2

Resources:
 Clone: clone-1
 Meta Attrs: interleave=true ordered=true
 Resource: res-1 (class=ocf provider=pacemaker type=controld)
  Operations: start interval=0s timeout=90 (dlm-start-interval-0s)
              stop interval=0s timeout=100 (dlm-stop-interval-0s)
              monitor interval=30s on-fail=fence (dlm-monitor-interval-30s)
 Group: grp-1
 Resource: res-1 (class=ocf provider=heartbeat type=IPaddr2)
  Attributes: ip=10.0.0.1 cidr_netmask=32
  Operations: monitor interval=120s (ip_monitor-interval-120s)
              start interval=0s timeout=20s (ip_-start-interval-0s)
              stop interval=0s timeout=20s (ip_-stop-interval-0s)

Stonith Devices:
Fencing Levels:

Location Constraints:
Resource: fence-1
    Disabled on: res-mgt (score:-INFINITY) (id:location-fence-1--INFINITY)
Resource: res-1
    Enabled on: res-mcast (score:INFINITY) (role: Started) (id:cli-prefer-res)
Ordering Constraints:
Colocation Constraints:

Resources Defaults:
 resource-stickiness: 100
 migration-threshold: 3
Operations Defaults:
 No defaults set

Cluster Properties:
 cluster-infrastructure: corosync
 cluster-name: cluster-1
 dc-version: 1.1.13-10.el7_2.4-44eb2dd
 have-watchdog: false
 no-quorum-policy: ignore
 stonith-enable: true
 stonith-enabled: false

The class provides attribute data as dictionary with lines parsed line by line based on keys, which are the key words of the output. Information in keys Corosync Nodes and Pacemaker Nodes is parsed in one line. The get method get(str) provides lines from data based on given key.

Examples

>>> pcs_config.get("Cluster Name")
'cluster-1'
>>> pcs_config.get("Corosync Nodes")
['node-1', 'node-2']
>>> pcs_config.get("Cluster Properties")
['cluster-infrastructure: corosync', 'cluster-name: cluster-1', 'dc-version: 1.1.13-10.el7_2.4-44eb2dd', 'have-watchdog: false', 'no-quorum-policy: ignore', 'stonith-enable: true', 'stonith-enabled: false']
>>> pcs_config.get("Colocation Constraints")
['clone-1 with clone-x (score:INFINITY) (id:clone-INFINITY)', 'clone-2 with clone-x (score:INFINITY) (id:clone-INFINITY)']
>>> 'have-watchdog' in pcs_config.cluster_properties
True
>>> pcs_config.cluster_properties.get('have-watchdog')
'false'

class insights.parsers.pcs_config.PCSConfig(context, extra_bad_lines=None)[source]¶

Bases: CommandParser

Class to process the output of pcs config command.

cluster_properties¶

A dictionary containing all cluster properties key, value

Type:: dict

data¶

A dictionary containing all line. Keys sorted based on keywords of the output. the form:

{
    "Cluster Name": "cluster-1",
    "Corosync Nodes": [
        "node-1",
        "node-2"
    ],
    "Pacemaker Nodes": [
        "node-1",
        "node-2"
    ],
    "Resources": [
        "Clone: clone-1",
        "Meta Attrs: interleave=true ordered=true",
        "Resource: res-1 (class=ocf provider=pacemaker type=controld)",
        "Operations: start interval=0s timeout=90 (dlm-start-interval-0s)",
        "stop interval=0s timeout=100 (dlm-stop-interval-0s)",
        "monitor interval=30s on-fail=fence (dlm-monitor-interval-30s)"
    ],
    "Cluster Properties": [
        "cluster-infrastructure: corosync",
        "cluster-name: cluster-1"
    ]
}

Type:: dict
