Events tab

The Events tab provides a feed which is a powerful feature that tracks events that happen on your infrastructure, or in your Space. The feed lets you investigate events that occurred in the past, which is invaluable for troubleshooting. Common use cases are ones like when a node goes offline, and you want to understand what events happened before that. A detailed event history can also assist in attributing sudden pattern changes in a time series to specific changes in your environment.

What are the available events?

At a high-level view, these are the domains from which the Events feed will provide visibility into.

Note

Based on your space's plan, different allowances are defined to query past data.

Topology events

Event name Description Example
Node Became Live The node is collecting and streaming metrics to Cloud. Node netdata-k8s-state-xyz was live
Node Became Stale The node is offline and not streaming metrics to Cloud. It can show historical data from a parent node. Node ip-xyz.ec2.internal was stale
Node Became Offline The node is offline, not streaming metrics to Cloud and not available in any parent node. Node ip-xyz.ec2.internal was offline
Node Created The node is created but it is still Unseen on Cloud, didn't establish a successful connection yet. Node ip-xyz.ec2.internal was created
Node Removed The node was removed from the Space, for example by using the Delete action on the node. This is a soft delete in that the node gets marked as deleted, but retains the association with this space. If it becomes live again, it will be restored (see Node Restored below) and reappear in this space as before. Node ip-xyz.ec2.internal was deleted (soft)
Node Restored The node was restored. See Node Removed above. Node ip-xyz.ec2.internal was restored
Node Deleted The node was deleted from the Space. This is a hard delete and no information on the node is retained. Node ip-xyz.ec2.internal was deleted (hard)
Agent Connected The Agent connected to the Cloud MQTT server (Agent-Cloud Link established).
These events can only be seen on All nodes Room.
Agent with claim ID 7d87bqs9-cv42-4823-8sd4-3614548850c7 has connected to Cloud.
Agent Disconnected The Agent disconnected from the Cloud MQTT server (Agent-Cloud Link severed).
These events can only be seen on All nodes Room.
Agent with claim ID 7d87bqs9-cv42-4823-8sd4-3614548850c7 has disconnected from Cloud: Connection Timeout.
Space Statistics Daily snapshot of space node statistics.
These events can only be seen on All nodes Room.
Space statistics. Nodes: 22 live, 21 stale, 18 removed, 61 total.

Alert events

Event name Description Example
Node Alert State Changed These are node alert state transition events and can be seen as an alert history log. You will be able to see transitions to or from any of these states: Cleared, Warning, Critical, Removed, Error or Unknown Transition to Cleared:

Transition from Cleared to Warning or Critical:
httpcheck_web_service_bad_status for httpcheck_netdata_cloud.request_status on netdata-parent-xyz was raised to WARNING with value 10%

Transition from Warning to Critical:
httpcheck_web_service_bad_status for httpcheck_netdata_cloud.request_status on netdata-parent-xyz escalated to CRITICAL with value 25%

Transition from Critical to Warning:
httpcheck_web_service_bad_status for httpcheck_netdata_cloud.request_status on netdata-parent-xyz was demoted to WARNING with value 10%

Transition to Error:
For this alert httpcheck_web_service_bad_status related to httpcheck_netdata_cloud.request_status on netdata-parent-xyz we couldn't calculate the current value ⓘ

Who can access the events?

All users will be able to see events from the Topology and Alerts domain, but Auditing events, once these are added, will only be accessible to administrators. For more details, check the Netdata Role-Based Access model.

How to use the events feed

  1. Click on the Events tab (located near the top of your screen)
  2. You will be presented with a table listing the events that occurred from the timeframe defined on the date time picker
  3. You can use the filtering capabilities available on the right-hand bar to slice through the results provided

Note

When you try to query a longer period than what your space allows, you will see an error message highlighting that you are querying data outside your plan.
