I have obtained the list of all alerts via REST API search as:
| rest /servicesNS/-/-/saved/searches search="is_scheduled=1" | table title | dedup title
Second, I have obtained the list of all triggered alerts via search:
search index="_internal" sourcetype="scheduler" thread_id="AlertNotifier*" alert_actions=email earliest = -24h | table savedsearch_name | rename savedsearch_name as title | dedup title
Also, there is a CSV file consisting of a list of hosts along with the list of alerts associated with the host.
The task we need to perform is to write a search that returns the list of all hosts along with the count of triggered alerts.
The problem we are facing is that the hosts which have no alerts triggered (but have configured alerts) are not showing up in the table, because those hosts are not being connected with the triggered alerts.
We are trying to solve the problem by retrieving the list of hosts from the configured alerts list and the count from triggered alerts list, but so far have been unsuccessful to devise a search.
I hope the issue is clear to understand.
Please suggest a suitable way to solve the problem.
