NETSIL AOC: Alerts¶
Alerts define health conditions for services. In this section we will walk you through setting up of Alerts in the NETSIL AOC and how you can use them to send notifications to responsible users via email, pagerduty, webhooks etc.
Creating An Alert¶
alerts tab, the user will see a summary dashboard of all alerts along with their trigger status. The trigger status is for the selected time window which can be adjusted using the time range slider. Color coding on alert trigger status implies:
- Red: critical threshold violation
- Orange: warning threshold violation
- Green: no violations
- Grey: "NO DATA" alert when data is missing for an expected metric
Note: It is recommended that users add group(s) in the
GroupBy field in the query builder for an alert if they would like to have alerts triggering based on each individual group, eg URIs. You can learn more about the
GroupBy field in the analytics documentation.
Alert tab showing summary of all alerts over selected time range
Clicking on any row will take the user to the alert page where the user can see the groups that have been triggered by that alert and modify the alert settings.
Global filters can be modified in the alert. Additional filters can also be defined in the query builder.
Setup and configure an alert
An example of a "no data" alert
Note: No data alerts are only applicable to metrics that have been seen in the past but are missing data in the evaluation window of the alert. If a metric has never been seen, then we don't trigger a "no data" alert for such metric since the system doesn't know that the data is missing.
User can receive notifications for an alert through email, webhooks, Pagerduty, etc. using
Configure notification settings.

Viewing Alert Status¶
On an alert page, under the
Status tab, the
All Groups tab shows all the groups associated with the alert. The user can also see
All Triggered Groups which contains all the groups that have triggered from among the groups that the user has selected in
http.uri) when creating an alert.
Users can add/remove/search for groups they are interested in from the filter bar. View triggered groups for an alert
