14. Alerts and Events¶
Robin CNS has a built-in alerting and event notification mechanism that enables a user to stay up to date with any meaningful events within the cluster. This is especially useful as it not only informs the user on system configuration changes but also occurrences that might impact applications and/or services on nodes in the cluster.
14.1. Events¶
Robin events are objects that provide a glimpse into operations that are occurring within the Robin cluster with regards to the underlying infrastructure and applications hosted on the hosts. These insights are generated regardless of the origin of the operation (manual intervention, Robin autopilot etc.) and span a variety of topics ranging from container relocation to temperature detection on hosts. Robin events are predetermined (identified by their type or unique id) and have three levels: INFO, WARN, ERROR. Each level is an indication of the severity of the event and consequently allows a user to distinguish which events they should be concerned about. In addition Robin events in the majority of cases come in pairs; one is raised during an occurrence of a negative scenario and another is raised when the scenario mentioned above is fixed (either by manual intervention or Robin auto-healing). The latter is known as a resolving event and is usually of the level INFO.
The following commands are described in this section:
|
List all events |
|
List all event-types |
14.1.1. Listing all events¶
Robin stores all events that have occurred during a cluster’s lifespan. To view these events, issue the following command:
# robin event list <id>
--page-size <page_size>
--page <page>
--hostname <hostname>
--type <type>
--type-id <type_id>
--level <level>
--object <object>
--ascending
--total
--json
|
ID of event to inspect. Note: This is an optional parameter. |
|
Maximum number of event records to include in a single output page |
|
Starting page number (relative to total number of pages of PAGE_SIZE |
|
Filter events to include only those originating from a particular host |
|
Filter events to include only those of a particular type |
|
Filter events to include only those with a particular type-id |
|
Filter events to include only those of a specific LEVEL |
|
Filter events to include only those which affect a particular object |
|
Return events in ascending order of ID |
|
Return the total number of events |
|
Display output in JSON format |
Example:
# robin event list

14.1.2. Listing event types¶
Robin has a set of predetermined events that are raised whenever the appropriate condition is met. They are identified by their type and their unique ID. The former gives an indication on what the event is referring. In addition, each event type has a status which refers to if the event is currently being tracked. To view all event types, run this command:
# robin event-type list <event_type>
--status <status>
--all
--json
|
ID of event type to inspect. Note: This is optional. |
|
Filter event types to include only those that match a particular status |
|
Display all event types regardless of status |
|
Display output in JSON format |
Example
# robin event-type list

EVENT_VOLUME_HIGHMARK
EVENT_DISK_SPACE_LIMIT_EXCEED
EVENT_NODE_VARLOG_HIGHMARK
EVENT_NODE_VARPGSQL_HIGHMARK
EVENT_NODE_VARCRASH_HIGHMARK
Run the following command to update the threshold limit:
# robin config update agent <attribute> <value>
Example:
# robin config update agent monitor_host_var_pgsql_volume_highmark 0.8
14.2. Alerts¶
Robin alerts are generated to notify the logged-in user that a negative event has occurred in the cluster. They are only generated when events at level WARN or ERROR are created. This is because these events might require immediate attention. Once an alert is raised, its state is set to ACTIVE. The alert will only be resolved if a resolving event is created or if a user manually resolves the alert.
The following commands are described in this section:
|
List all alerts |
14.2.1. Listing all alerts¶
Events of level ERROR or WARN are considered to be alerts as they need to be resolved before they can be dismissed. Robin stores all alerts that have occurred during the lifespan of a cluster. To view these alerts, run this command:
# robin alert list <id>
--page-size <page_size>
--page <page>
--hostname <hostname>
--nodeid <node_id>
--type <type>
--type-id <type_id>
--level <level>
--object <object>
--all
--ascending
--total
--json
|
ID of alert to inspect. Note: This is an optional parameter. |
|
Maximum number of alert records to include in a single output page |
|
Starting page number (relative to total number of pages of PAGE_SIZE) |
|
Filter alerts to include only those originating from a particular host |
|
Filter alerts to include only with a particular node ID |
|
Filter alerts to include only those of a particular event type |
|
Filter alerts to include only those with a particular event type-id |
|
Filter alerts to include only those of a specific LEVEL |
|
Filter alerts to include only those which concern a particular object |
|
Return all alerts, even those that were resolved |
|
Return events in ascending order of ID |
|
Return the total number of alerts |
|
Display output in JSON format |

14.3. Notification of events¶
Robin provides a native mechanism to instantly notify parties of any events that may concern them. This feature is useful as it enables quick responses to failures of cluster-wide resources and infrastructure.
The parties are modeled as subscribers in Robin and will need to be added manually, along with the method used to notify them. Given the large number of events that are detected by Robin, a subscription to a specific event is needed to indicate that a particular event is of interest. Each subscriber is then notified when the event that is tied to a subscription occurs.
To summarize, receiving a notification for an event is a two step process:
Add a subscriber and their contact details
Add a subscription to an event that is of interest
Described below are the commands used to manage subscribers and subscriptions.
14.3.1. Managing subscribers¶
Subscribers are the intended recipients of notifications and should be configured before adding a subscription.
The following commands are described in this section:
|
Add a subscriber |
|
List all subscribers |
|
Update a subscriber’s attributes |
|
Remove a subscriber |
14.3.1.1. Registering a Robin subscriber¶
To add a new subscriber to the system, run this command:
# robin subscriber add <name> <subscriber_type>
--email-address <email_address>
--full-name <full_name>
--host <host>
--port <port>
--community <community>
Note
For email subscribers the parameters email-address and fullname are mandatory. On the other hand, for SNMP subscribers the parameters host, port and community are mandatory.
|
Name to assign to subscriber |
|
Type of subscriber. Options include: snmp, email |
|
Email address of subscriber |
|
Full name of subscriber |
|
SNMP Host for subscriber |
|
SNMP Port of subscriber |
|
SNMP Community of subscriber |
Example
# robin subscriber add demo_user email --email-address demo@robin.io --full-name Robin
Successfully added subscriber 'demo_user' with 'email' notification
Note
A user with the same name can be both an email and SNMP subscriber.
14.3.1.2. Listing all subscribers¶
To list all of the subscribers currently registered with Robin alongside details such as the subscription type and ID, issue the following command:
# robin subscriber list <id>
--name <name>
--type <type>
--json
|
ID of subscriber to inspect (optional). |
|
Name of subscriber to inspect |
|
Filter subscribers to include only a particular type of subscriber |
|
Display output in JSON format |
Example
# robin subscriber list
ID | Name | Type | Details
---+-------+-------+--------------------------------------------------------
56 | demo | email | Full name: demo user, Email Address: demo@robin.io
56 | demo | snmp | Host: cscale-82-45, Port: 162, Community: public
Returns all of the subscribers currently registered with Robin alongside details such as the subscription type and ID.
End Point: /api/v3/robin_server/subscribers/
Method: GET

},
"snmp":{
"id":1,
"host":"cscale-82-45",
"port":162,
"community":"public"
}
}
]
}
14.3.1.3. Updating a subscriber¶
To update one or many attributes of a subscriber, run this command:
# robin subscriber update <id>
--email-address <email_address>
--full-name <full_name>
--host <host>
--port <port>
--community <community>
