> Add one more publish implement (Slack) for Alert.
> How to implement
> 1. Here uses a lib "simple-slack-api" to connecting to Slack and publish
> alert messages to Slack.
> 2. Add one more publisher of Slack which extends "AbstractPublishPlugin" to
> process received AlertStreamEvent, and according to Slack config which
> defined in publishment.json to send messages.
> How to use
> 1. Create a bot user in Slack, and remember its token.
> 2. Create some channels if you want send messages to if they do not exist.
> 3. Add your bot user to these channels.
> 4. Then define Slack config and declare to use Slack publisher in config file
> such as below (Especially the "type" and "properties". Here urltemplate will
> form an output url link based on docId if downstream have it.), we can use it
> very easily:
> {
> "name": "test-slack-output",
> "type":
> "org.apache.eagle.alert.engine.publisher.impl.AlertSlackPublisher",
> "policyIds": [
> "switch_check"
> ],
> "properties": {
> "token": "your token",
> "channels": "your channel1, your channel2",
> "severitys": "CRITICAL",
> "urltemplate": "your template/?id=%s"
> },
> "dedupIntervalMin": "PT1M",
> "dedupFields": [
> "appname"
> ],
> "serializer":
> "org.apache.eagle.alert.engine.publisher.impl.StringEventSerializer"
> }
> Something about the metadata schema
> 1. token: your bot user token.
> 2. channels: Slack channel names.
> 3. severitys: which severity level alert message you want to send to Slack.
> Other level message will be skipped.
> 4. urltemplate: used to form an output url link based on docId if downstream
> have it. A typical use case will be that downstream stored all the alerts in
> Elasticsearch, so we can previously append an ES link in the slack message.
