Multiple regex matching in filebeat for message field - regex

Question

I want to apply 2 regex expression with filebeat to drop events matching the content in message field.
I am able to make it work for single regex condition, but I am not sure how to configure multiple regex conditions.
regex list:
message: "(?i)cron"
message: "^now ([0-9]{4})-([0-1][0-9])-([0-3][0-9])\s([0-1][0-9]|[2][0-3]):([0-5][0-9]):([0-5][0-9])$"
Following is the config I have done for single regex which will match "cron" case insensitive text anywhere in the message
- drop_event:
when:
regexp:
message: "(?i)cron"
Refering to the Filebeat docs, I tried multiple configs but then filebeat won't startup:
Try 1:
- drop_event:
or:
- regexp:
message: "(?i)cron"
- regexp:
message: "^now ([0-9]{4})-([0-1][0-9])-([0-3][0-9])\s([0-1][0-9]|[2][0-3]):([0-5][0-9]):([0-5][0-9])$"
Try 2:
- if:
regexp:
message: "(?i)cron"
then:
drop_event:
- if:
regexp:
message: "^now ([0-9]{4})-([0-1][0-9])-([0-3][0-9])\s([0-1][0-9]|[2][0-3]):([0-5][0-9]):([0-5][0-9])$"
then:
drop_event:

Answer 1

Figured Out How we can apply multiple filter using or operator in filebeat. I was close in the second attempt in the post. When is required, after that we can use whatever operator we like or and etc.
Here's example of how I am using it
processors:
- drop_event.when:
or:
- contains:
container.name: "nginx"
- contains:
container.name: "mongo"
- contains:
container.name: "mysql"
- contains:
container.name: "redis"
- equals:
container.name: "tecnativa/tcp-proxy"
- drop_event.when:
or:
- regexp:
message: "(?i)cron"
- regexp:
message: "In On Child added message"
- regexp:
message: "In on Child removed message"
- regexp:
message: "then Moment"
- regexp:
message: "call_duration"
- regexp:
message: "now Moment"
- regexp:
message: "CHAT NOTIFICATION CODE"
