I want to process logs separated by pipe '|' operator in an ingress pipeline using grok. How can I ignore this character in the pattern?
Log data:
```auto
PUT /combined/_doc/1?pipeline=pipeline_combined_logs
{
"service": "ise7085|19524"
}
```
Pattern:
```auto
{
"grok": {
"field": "service",
"patterns": "%{DATA:user}\|%{DATA:pid}"
}
}
}
```
Above pattern throw error
```auto
"Unrecognized character escape '|'
```
Thanks!!!

You need to use a double backslash
```
"patterns": "%{DATA:user}\\|%{DATA:pid}"
```

@val I tried your suggestion but it parses only user and pid field has no value now.

Try `INT` instead of `DATA`
