Webscale Monitoring Agent on Webscale Product Documentation

Configuring WMA

Mon, 01 Jan 0001 00:00:00 +0000

The Webscale Monitoring Agent (WMA) is a multipurpose program that can be installed on a VM host to facilitate communication with Webscale. It consists of three independent processes—metric monitoring, log collection , and SSH connectivity —which you can enable or disable in the configuration file.

Configuration reference

Configure the Webscale Monitoring Agent using the file /etc/webscale/wma-config.json. The Webscale control plane automatically supplies some configuration values for VMs it creates. The file is in JSON format with the following fields.

Log Collection

Mon, 01 Jan 0001 00:00:00 +0000

The Webscale Monitoring Agent can be configured to aggregate logs in the Webscale Control Panel for easy filtering, searching, and viewing. This is done by enabling log collection in the WMA configuration file.

Logs are aggregated as “Custom Logs” and can be viewed in the Webscale Control Panel. For more information, see Configuring and Viewing Custom Logs .

Log streams

A log stream is simply a collection of logs, aggregated for easy filtering and searching

SSH Connect

Mon, 01 Jan 0001 00:00:00 +0000

The Webscale Monitoring Agent can be used to facilitate easy SSH access to authorized users directly via the Webscale Control Plane. Enabling SSH Connect within WMA will register the host with the Webscale Control Plane and allow the WMA to manage Webscale users on the host.

Registration

In order to connect to a host via SSH Connect, that host must be registered with Webscale. (See SSH Connect documentation for more details on registration .) When WMA is started with ssh enabled, the WMA will attempt to register the host automatically. Upon successful registration, it will then subscribe to Webscale’s Pub/Sub API to receive any user updates for the host. This allows users to be created and removed on the host as needed by the SSH Connect facility. (See Connecting to Hosts
