Log Parser Input Plugin does not work on RHEL 5

[sudharani-m]

Hello Team,

We are running telegraf version v1.2.1 in RHEL 5 server. We are using log parser plugin to send CPU info. However while running the telegraf agent we are getting following error message.
Telegraf.conf file
[inputs.logparser.grok]
    patterns = ["%{DATA:host_name:tag} %{DATA:metric:tag} %{NUMBER:mft_value:float}"] 

Error:

Do we have RHEL compatibility issue with this plugin?

Seems like a compatibility issue, can you add the output of uname -a.

If you are able can you git clone https://github.com/fsnotify/fsnotify and run git test ./...

To solve this we need someone to check if the fsnotify tests work on RHEL or Centos 5. I'm assuming the tests will fail, and then we can open a ticket upstream.

In version 1.5 we are adding a watch_method = "poll" option which I believe will be a workaround for this issue.

Closing, RHEL5 users should use the poll method.
