Question: If NSFW is down, then how can a user
identify it?
Answer
If NSFW is down, then the notification service generates a heartbeat alert. And, a heartbeat alert gets closed once NSFW is up.
There is a delay of 5 minutes for the alert to generate because NSFW is sending the heartbeats every 5 minutes. If NSFW is
down for a longer period, then the last updated time of the heartbeat alert gets updated instead of creating lots of alerts.
Issue: Alerts in real time
Question
Are the alerts seen in real time if they are disabled at 9 a.m. and enabled at 10 a.m., or will get the alerts from 9 a.m.?
Answer
Alerts are seen in real time, disabled alert are not shown in UI from 9 a.m. to 10 a.m time period.
Question: How can a user read alerts from a node?
Answer
The Customer Support engineers can log in and get the database details.

| \
> grep -v _timescaledb_internal > system_alert.sql
psql -d notification -U notification \
> -c "\COPY (SELECT * FROM system_alert) TO system_alert.csv DELIMITER ',' CSV"

Issue: SMTP server is not reachable.
Answer
The Notifications service tries to send out the mail with failover. After 20 seconds, user can quit. The mail will not be sent for
that alert, and user can move onto the next.
