Overview

This plugin provides a way for the PSM customers to use PSM plugins written in Ruby in AppOptics (including their own custom plugins). If PSM customers migrate to AppOptics, they will no longer have access to the PSM UI or PSM’s remote configuration. In this case, customers can still use PSM’s Ruby plugins, but they need to place those files on their servers themselves manually or via configuration management of choice (Ansible, Salt, etc).

This plugin is currently available for x86_64 Linux platforms.

Setup

The psm plugin is included with the SolarWinds Snap Agent by default. It’s an adapter for Ruby plugins written originally for PSM/Scout.

If you are a Scout client willing to migrate to AppOptics, please use the dedicated tool: https://github.com/pingdomserver/scout-ao

Prerequisites

This plugin requires that Ruby is available and Scout is installed but inactive on the target host.

Configuration

Normally you won't need to change anything here, the migration script does all the necessary setup.

• If you wish to change the collector plugin settings, edit its configuration file /opt/SolarWinds/Snap/etc/plugins.d/psm.yaml:

        ## Most probably you won't need to change those fields and may safely rely on the defaults
        ## For detailed configuration documentation please refer to https://server-monitor.readme.io/docs/agent

  load:
    plugin: snap-plugin-collector-psm
    task: task-psm.yaml

  The setting ruby_path is optional and defaults to the First ruby found in $PATH.

  The setting agent_ruby_bin is optional and defaults to /usr/share/scout/ruby/scout-client. It is an installation path of scout-client.

  The setting plugin_directory is optional and defaults to /opt/SolarWinds/Snap/bin/psm. It is a path to where the PSM plugins .rb files were downloaded (along with the corresponding .yaml files holding particular configs).

  The setting agent_data_file is optional and defaults to /var/lib/scoutd/client_history.yml.

  For more detailed configuration documentation please refer to scoutd docs

• If you wish to change the collector task settings, edit its configuration file /opt/SolarWinds/Snap/etc/tasks.d/task-psm.yaml:

To make changes happen, restart the agent:

Copy

$ sudo service swisnapd restart

Unless you already did so, enable the PSM plugin in the AppOptics UI:

On the Integrations Page you will see the PSM plugin available. If you do not see the plugin, see Troubleshooting Linux.

Metrics

Metrics will appear as psm.plugin.<your_plugin_name>.<data_field_name>. As each customer has his/her own tailored set fo plugins, there’s no predefined default dashboard for this integration.

Tags

Each metric is annotated with the following tags:

Tag name	Meaning
hostname	Name of the host on which scout was running (used for host identification by the PSM API).
environment	Annotation used in PSM for configuring different notifications for eg. production and staging servers. See the environments page in the PSM/Scout docs for more
roles	Annotation used in PSM that let configuring servers in bulk. Servers could belong to many roles. See the roles page in the PSM/Scout docs for more
local_filename	Name of the .rb file that reported metric
origin	Origin of the plugin (eg. ‘local')
plugin_id	Identificator of the original PSM/Scout plugin.
