[Monitoring plugin upgrade] Announcement on enabling the O11yAgent collection solution

Dear VolcanoEngine users,to enhance the efficiency and flexibility of monitoring data collection, VolcanoEngine will fully adopt O11yAgent as the standard collection plugin for ECS instances to replace cloud-monitor-agent. We sincerely recommend that you upgrade to O11yAgent.

tip

After this, the old collection plugin cloud-monitor-agent will only be maintained for existing scenarios and will not be added with new monitoring metrics.

Applicable scenarios

If you have any of the following requirements, we strongly recommend that you immediately install or upgrade to theO11yAgent collection plugin.

You need long-term monitoring and monitoring metric observation capability that supports sustainable iteration.

You need to visually manage the monitoring plugin to achieve one-click deployment and status monitoring.

You need more monitoring metrics to increase O&M granularity, such as the metrics of "Total number of processes" and "GPU decoder usage".

Comparison of new and old plugins

Plugin	Plugin name	Scope	Differences
New plugin	O11yAgent	Infrastructure/operating system monitoring Process monitoring GPU/RDMA monitoring	The plugin is a new-generation observability data collection plugin that fully covers all monitoring metrics of cloud-monitor-agent. Additionally, it adds more monitoring metrics to meet your needs for higher monitoring granularity. The plugin provides white-screen installation/upgrade interfaces, one-click deployment and status monitoring, and user-friendliness. It will be the default collection plugin for new ECS instances, and new monitoring metrics will only be added based on the O11yAgent plugin.
Old plugin	cloud-monitor-agent	TCP link monitoring Infrastructure/operating system monitoring Process monitoring GPU/RDMA monitoring	It is currently the default collection plugin for ECS instances. The plugin does not provide a white-screen operation interface and the operation is more complex than O11yAgent. Subsequently, the legacy plugin cloud-monitor-agent will only be maintained for existing scenarios, and no new monitoring metrics will be added.

Impact on you

The O11yAgent collection pluginsupports all monitoring metrics of the cloud-monitor-agent collection plugin. The upgrade is simple, does not affect operations of your existing services, and does not require reconfiguration of alert rules. O11yAgent has more advantages than the cloud-monitor-agent plugin.
