I have build a custom plugin for my logstash. I made it's gemfile using gemspec file then i installed the plugin.
when i check for my plugin with command:
`bin\logstash-plugin list --verbose`
`logstash-filter-jwt (0.1.0)`
it is present in the list, but when i try to run my logstash which calls in the plugin, then it throws me an error -
`[2018-02-02T15:52:49,333][ERROR][logstash.agent] Cannot create pipeline {:reason=>"Couldn't find any filter plugin named 'jwt'. Are you sure this is correct? Trying to load the jwt filter plugin resulted in this error: Problems loading the requested plugin named jwt of type filter. Error: NameError NameError"}`
my logstash looks like this -
input {
beats {
port =\> "5044"
client\_inactivity\_timeout =\> "120"
#Uncomment below SSL configurations and put appropriate values in each configuration to enable SSL/TLS communication between Logstash and Filebeat
#ssl =\> true
#ssl\_certificate =\> "/opt/grace/config/logstash-forwarder.crt"
#ssl\_key =\> "/opt/grace/config/logstash-forwarder.key"
}
}
filter {
```
jwt{
secretkey => "Eg=C}k!5]YG`d{*`#dDZd4=*"
}
```
}
output{
}
I wanted to know that why my logstash is unable to recognise my plugin ?
If you have any suggestions, solutions, workarounds then do share. 🙂
