How to monitor Elasticsearch snapshots

I'd like advice on how to monitor snapshots. Is there a way to do it via a monitor? We'd only want the status of the last snapshot taken (report either success or failed).

You can use the 'Get Snapshot Status API'

I want this to alert me via a monitor if the last snapshot fails. I won't know the snapshot name because we use SLM which appends the unique identifier. Wouldn't I need to know the snapshot name to get the details of the last snapshot with this command?

The goal is to create an automated check that would run every X minutes to check the status of the last snapshot. It would then email me the status (success or fail).

Here's how I could do it if I knew the name of the snapshot (snapshot name is v780nightlysnap-2020.11.20-mrage5htsvihwjav6mca5w). The problem is I don't know of a way to get the name of the last snapshot.

  "trigger": {
    "schedule": {
      "interval": "30m"
  "input" : {
    "http" : {
      "request" : {
        "host" : "localhost",
        "port" : 9200,
        "path" : "_snapshot/<repo>/v780nightlysnap-2020.11.20-mrage5htsvihwjav6mca5w"
  "actions": {
    "email_action": {
      "email": {
        "to": "",
        "subject": "Snapshot status",
        "body": "Snapshot status is {{ctx.payload.snapshots.0.state}}"

You can get all snapshots, either from a specific repository or from all repositories. And then filter for the last one/top one.

I haven't been able to figure out how to filter for just the last one. Do you have sample code for how to do that?

Search for top hits.
There are multiple examples out there.
By the way, why you are not using an elastic query?

Thanks for the information. I'll check on the top hits. Out of curiosity how would I be able to do a query against the snapshot repository? I tried using _search, but it comes up with no handler found for uri [/_cat/snapshots//_search] and method [GET]. Unfortunately I'm new to elasticsearch. I'm a database administrator that has recently also become the ElasticSearch admin for storage related tasks.

You can't for now. You need to restore first.
It will be supported in the future with the frozen tier.

Thanks for the info. I guess I'll have to continue logging in on the weekends to make sure the last snapshot was successful and current.

Not sure I understood the last part.

If you snapshot your index and have at the end a success status, you'll be all good.

We currently do a snapshot daily via SLM. What I'm trying to do is have some sort of automated daily process that sends me an e-mail with the status of the last snapshot and if it was current so I don't have to check it manually. This would be especially handy on weekends and holidays. Right now I login daily to check it.

I'd like to complete my previous answer by linking to this new feature in 7.10.
