 9 | > Module that sends logs of processes controlled by [PM2](https://pm2.io) to Elasticsearch 📒🔍
10 | 
11 | 
12 | ## Install
13 | 
14 | `pm2 install pm2-elasticsearch-logger`
15 | 
16 | 
17 | ## Configuration
18 | 
19 | Set options with the command
20 | 
21 | `pm2 set pm2-elasticsearch-logger:<option> <value>`
22 | 
23 | PM2 will automatically restart the module after changing an option.
24 | 
25 | #### Options
26 | 
27 | | option |           | default |
28 | | ------ | --------- | ------- |
29 | | elasticUrl | URL of Elasticsearch API | `http://localhost:9200` |
30 | | insecure | allow https connections to servers with invalid certificate | `false` |
31 | | index | Elasticsearch index to use | `pm2` |
32 | | type | Document type to use | `pm2` |
33 | | host | `host` attribute of the document | `os.hostname()` |
34 | 
35 | 
36 | ## Todo, Ideas
37 | 
38 | * Configurable document attributes
39 | * Create mapping for `@timestamp` only if neccessary, control by config option
