Opsview - dosh – Support - ITRS Group

Run a given command on specified Opsview hosts.

Synopsis

/opt/opsview/support-scripts/bin/dosh
dosh -l
dosh -t opsview_collectors <command to run>

Run a given command on a selection of the Opsview hosts by using the Ansible ‘shell’ module.

Must be run on your deployment host as the root user. Requires the utility jq be installed.

Option	Purpose	Default
`-h`	Terse help output
`-l`	List available host groupings
`-m <module>`	Specify the Ansible module to use	Shell
`-t <target>`	Set the host grouping to `<target>`	`opsview_collector:!opsview_orchestrator`

Argument	Purpose
`<commands to run>`	The command to run on the remote servers (or arguments to pass to the Ansible module)

File	Description
`/opt/opsview/deploy/etc/opsview_deploy.yml`	Configuration file used by Ansible

/opt/opsview/supportscripts/bin/dosh -t opsview_collectors hostname

/opt/opsview/supportscripts/bin/dosh -t opsview_cluster_cluster_fr uptime -p

Run cat /opt/opsview/var/machine.ref on all collectors but not the orchestrator:

/opt/opsview/supportscripts/bin/dosh -t 'opsview_collector:!opsview_orchestrator' cat /opt/opsview/var/machine.ref

You can achieve the same effects of dosh by using Ansible on your orchestrator.

Before running any of the following commands for the first time in a shell session, you need to log in as root and use this source command:

source /opt/opsview/deploy/bin/rc.ansible

This command requires the jq package be installed.

ansible-inventory  --list | jq -r '.opsview_all.children[]'

ansible -m shell -a '<command>' '<hosts>'

For example, run hostname on every Opsview host:

ansible -m shell -a 'hostname' 'opsview_all'
