Managing Apache ActiveMQ
Manage monitoring thresholds and perform remote administrative actions on Apache ActiveMQ queues and services.
This agent allows you to monitor and manage content on Apache ActiveMQ queues.
Delegate the power to control all or individual Apache ActiveMQ resources to selected team members and the business. This feature helps the people involved in the support and maintenance team have the power to manage problems with your Queues and services without having individual direct access to the Web-based admin pages in Apache ActiveMQ. Limiting the number of attack vectors and having fewer people with high access rights minimizes the risk of disruption of mission-critical services.
Stockpiling messages is terrible for your business. So we developed this Monitoring Agent to give end-users the power to get alerts and manage content to keep the system healthy.
Monitoring Features
The Agent monitors the following resources:
- ActiveMQ Brokers
- The server(s) and core services
- ActiveMQ Queues
- Age verification (warning/error) - Set the maximum allowed age for messages on the queue
- Count (warning/error) - Set the maximum allowed message count on the queue
You can individually fine-tune the Monitoring thresholds per queue.
Actions
A User with access rights to a Monitor View with ActiveMQ Queues where Actions are allowed can perform the following Actions:
- Edit thresholds
- List Messages on queue
- Repair/View message
- Download individual messages from the queue with the encoding option
- Download selected messages in a ZIP file (with the encoding option)
- Delete one or more messages from the queue
Edit Thresholds
The Monitoring thresholds are global or specific. Whenever you set a value on a queue, it becomes a specific configuration. This configuration applies only to this queue, regardless of settings for other queues.
You can either use the global settings for the queue using Remote Configuration, or you can individually set different thresholds for different queues.
When you opt to save, the Resource changes to a "Specific ActiveMQ Queue" (may impact your Monitor Views depending on filter).
List messages on the queue
From within the 'List messages on the queue' modal, a paged list of messages currently on the queue is displayed. The messages displays with evaluation according to the monitoring thresholds (either global or specific).
The following remote Actions can be performed using the With selected button:
