Error when startingmetricbeat with v7.5.3

vee · March 20, 2020, 9:14pm

I see this error when trying to start metricbeat on ppc64le system:

2020-03-20T15:47:22.639-0500 ERROR pipeline/output.go:100 Failed to connect to backoff(elasticsearch(http://elasticdev:9200)): Connection marked as failed because the onConnect callback failed: resource 'metricbeat-7.5.3' exists, but it is not an alias

Here's the command to start:

metricbeat -E path.config=/tmp/metricbeat -e -c /tmp/metricbeat/metricbeat.yml

Here is the metricbeat.yml:

Could you make the following Elasticsearch API calls and post their results here please?

GET _cat/indices/metricbeat-*?v

GET _cat/aliases/metricbeat-*?v

GET _template/metricbeat-*

Thanks,

Thanks. So the problem is that somehow there is a metricbeat-7.5.3 index, whereas Metricbeat is expecting this to be an alias.

At this point, I'd suggest the following steps:

Stop all instances of Metricbeat 7.5.3.
Delete the metricbeat-7.5.3 index as it doesn't have any documents in it:
```
DELETE metricbeat-7.5.3
```
Delete the Metricbeat 7.5.3 index template.
```
DELETE _template/metricbeat-7.5.3
```
Restart the stopped Metricbeat instances. This should recreate the template, the index alias, and the correct index.

Tried to delete the metricbeat and it's template v7.5.3 - and when restarted, I still see the same error.

That's strange. Thanks for posting the logs. These messages in your log look odd to me:

2020-03-24T13:19:46.233-0500    INFO    [index-management.ilm]  ilm/std.go:138  do not generate ilm policy: exists=true, overwrite=false

Could you post the entire contents of your metricbeat.yml please (after redacting any sensitive information)?

Thanks,

Shaunak

Never mind, please ignore my last post. I see that you posted your metricbeat.yml above already!

Could you try commenting out this line from your metricbeat.yml?

setup.template.enabled: false

And then restart Metricbeat and check things again?

Thanks,

Shaunak

I dug around the code where this log message is being generated from:

2020-03-24T14:20:51.511-0500    INFO    [index-management.ilm]  ilm/std.go:138  do not generate ilm policy: exists=true, overwrite=false

Long story short, it looks like we're running into this bug: Change `setup` behavior to respect `ilm.overwrite` setting · Issue #14735 · elastic/beats · GitHub. The bug was fixed in https://github.com/elastic/beats/pull/14741 and the fix was released in Metricbeat 7.6.0. Would it be possible for you to try out that version?

Downloaded v7.6.0, tried with both setup template enabled & commented out in metricbeat.yml, but still see errors:

Hmmm, could you check one more thing in Elasticsearch please?

GET _ilm/policy

Is there one (or more) returned for Metricbeat?

Thanks, that looks OK to me. The upgrade might've been a red herring.

Looking at the error in your logs (pre- and post-upgrade):

Cannot write to a field alias [event.module]

I'm now wondering if there's an old Metricbeat template that's resulting in a mapping conflict, similar to the one described in Filebeat errors after update to version 7 - #11. Can you look through your Metricbeat templates (output of GET _template/metricbeat-*) to see if there's one that matches the index pattern metricbeat-*?

vee · March 25, 2020, 3:27pm

I checked that and removed any metricbeat templates newer than v7. However, I still see this error even though the template does not exist when I tried to start metricbeat:

Is there some sort of cache that should be cleared to flush out any existing templates?

shaunak · March 25, 2020, 3:41pm

No, there is no cache.

I see that now the resource 'metricbeat-7.6.0' exists, but it is not an alias error has come back.

In addition to deleting any Metricbeat templates with index_patterns as metricbeat-* (i.e. a template that would very broadly match all indices starting with metricbeat-), could you also follow the steps in Error when startingmetricbeat with v7.5.3, but for 7.6.0 this time?

Shaunak
