How will i know that elasticsearch has crashed or stopped working?

[Shrimp-Fried-Rice]

i have few questions in mind,

1. Is there way to get notified if elasticsearch crashes or stops working ?

2. is there system in place to auto start elasticsearch if it crashes ? just like in mysql ?

3. can i start elasticsearch and forget about it ? its been running from last 4 days without any issues.
   i mean, i can rest in peace knowing that website searches are working properly ?

4. or does it need regular/constant monitoring ?
   if yes, then what type of monitoring ?

right now i am monitoring from kibana > monitoring > indices > my_index

Thanks for your time
have a great day ahead.

Do you monitor other systems you have in place? This isn't a question specific to Elasticsearch

i monitor site uptime using pingdom, aka nginx , phpfpm

mysql has auto restart after crash.

Thanks

You can call HOST:9200 and that will tell you if that host is running Elasticsearch properly.
You can also use things like https://www.elastic.co/products/x-pack/monitoring

There's no way to auto restart it though.

Thank you, that will work.,

checking if curl request to 9200 comes back positive and do accordingly.
