ES 1.1.1 - Plugins _site not found

Elastic Stack Elasticsearch
1

Has anyone else ran into this?

We didn't have this behavior on 90.5. While testing out 1.1.1 it seems to
happen every minute in the logs for both of the plugins we use which are
siteless. If i create an empty _site directory for the plugins then the
log entries immediately stop. I've also confirmed that elasticsearch does
start up properly with the empty _site directory. I couldn't find anything
in the documentation about changes to plugins and the _site directory.
Curious if anyone else has experienced this, and what they did.

Each time you start a node, may it be a (transport) client node or a server
node, all plugins are checked/loaded at initialization.

Each plugin, also jvm plugins on the classpath, is by default examined if a
directory named "_site" can be accessed. The purpose is to classify a
plugin as site plugin. A method in FIleSystemUtils logs if the directory
has problems. So the log message is completely harmless, especially for jvm
plugins without a _site.

Note, if you see this every minute, you should research if there is
something running in your ES that initiates a (client) node at that
frequency. In most cases, this is not required.

I ran into the same issue when I upgraded to 1.x. The code in the plugin
service will scan the plugins every minute. You can either disable the
lookup or reduce the logging level (which is what I did).

Thanks for the tip. Found that our Sensu monitoring is doing some api
calls for monitoring cluster health that are triggering the log entry.
Mystery solved. Thank you.

This could help: Elasticsearch Platform — Find real-time answers at scale | Elastic

if your plugin data is subject to change use plugins.info_refresh_interval to change or disable the caching interval:

Change cache to 20 seconds

plugins.info_refresh_interval: 20s

Infinite cache

plugins.info_refresh_interval: -1

Disable cache

plugins.info_refresh_interval: 0
