Events feed
Netdata Cloud provides the Events 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.
⚠️ Based on your space's plan, different allowances are defined to query past data.
| Domains of events | Community | Pro | Business |
|---|---|---|---|
| Auditing events - Events related to actions done on your Space, e.g. invite user, change user role or change plan. | 4 hours | 7 days | 90 days |
| Topology events Node state transition events, e.g. live or offline. | 4 hours | 7 days | 14 days |
| Alert events Alert state transition events, can be seen as an alert history log. | 4 hours | 7 days | 90 days |
Auditing events
| Event name | Description | Example |
|---|---|---|

| Room Created | A room was created on the Space. | Room DB Servers was created by John Doe |
| Room Deleted | A room was deleted from the Space. | Room DB servers was deleted by John Doe |
| User Invited to Space | A user was invited to join the Space. | User John Smith was invited to this space by Alan Doe |
| User Uninvited from Space | An invitation for a user to join the space was revoked. | User John Smith was uninvited from this space |
| User Added to Space | A user was added to the Space from an invitation (user accepted the invitation). | User John Smith was added to this space by invite of Alan Doe |

| User Added to Room | A user was added to a room on the Space. | User John Smith was added to room DB servers |
| User Removed from Room | A user was removed from a room on the Space. | User John Smith was removed from room DB Servers by Alan Doe |
| User Space Properties Changed | The properties of a user on the Space have changed, e.g. change user role | User role for John Smith was changed to troubleshooter by Alan Doe |
| Node Added To Room | The node was added to a room on the Space. | Node ip-xyz.ec2.internal was added to room DB Servers by John Doe |
| Node Removed To Room | The node was removed from a room on the Space. | Node ip-xyz.ec2.internal was removed from room DB Servers by John Doe |
| Silencing Rule Created | A new alert notification silencing rule was created on the Space. | Silencing rule DB Servers schedule silencing on rooms All nodes and DB Servers was created by John Smith |
| Silencing Rule Changed | An existing alert notification silencing rule was modified on the Space. | Silencing rule DB Servers schedule silencing on rooms All nodes and DB Servers was changed by John Doe |
| Silencing Rule Deleted | An existing alert notifications silencing rule was removed from the Space. | Silencing rule DB Servers schedule silencing on rooms All nodes and DB Servers was changed by Alan Smith |
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 War 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 War 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 War 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:httpcheck_web_service_bad_status for httpcheck_netdata_cloud.request_status on netdata-parent-xyz recovered with value 8.33%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 Removed: Alert httpcheck_web_service_bad_status for httpcheck_netdata_cloud.request_status on netdata-parent-xyz is no longer available, state can't be assessed.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, only be accessible to administrators. For more details checkout Netdata Role-Based Access model.
How to use the events feed
- Click on the Events tab (located near the top of your screen)
- You will be presented with a table listing the events that occurred from the timeframe defined on the date time picker
- You can use the filtering capabilities available on right-hand bar to slice through the results provided. See more details on event types and filters
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 of your plan.
