aarishramesh · May 24, 2017, 1:05pm

I am trying to install elasticsearch curator by various means like

pip install elasticsearch-curator

But when i execute the above command I get a series of errors like below

Also when i try to execute it like below

sudo apt-get update && sudo apt-get install python-elasticsearch-curator

What is the problem here wrt to installing elasticsearch-curator as I am just following the instructions in the installation page ?

theuntergeek · May 24, 2017, 1:54pm

Which documentation link are you looking at? When I look at the current documentation, I see:

sudo apt-get update && sudo apt-get install elasticsearch-curator

but you have

sudo apt-get update && sudo apt-get install python-elasticsearch-curator

I tried executing the command too

sudo apt-get update && sudo apt-get install elasticsearch-curator

But still the error persists

theuntergeek · May 24, 2017, 3:51pm

I see packages.elastic.co/elasticsearch/5.3.0, but Curator is in a different path. Did you follow these instructions to add the Curator repository properly?

aarishramesh · May 26, 2017, 11:57am

Yes @theuntergeek I have followed the steps properly. Can't understand why does the package not found error occurs ?

theuntergeek · May 26, 2017, 2:10pm

Neither can I. I just spun up a clean Ubuntu 16.04 VM:

Locale fix (for my VM). You may or may not need to do this if a UTF-8 charset is your default locale.

root@ubuntu1604-test:~$ locale-gen "en_US.UTF-8"
/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf8)
Generating locales (this might take a while)...
  en_US.UTF-8... done
Generation complete.
root@ubuntu1604-test:~$ dpkg-reconfigure locales

Now, the install:

root@ubuntu1604-test:~$ wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
OK
root@ubuntu1604-test:~$ echo "deb http://packages.elastic.co/curator/5/debian stable main" > /etc/apt/sources.list.d/curator.list

What's in your repository definition? Is it "deb http://packages.elastic.co/curator/5/debian stable main"?

Thanks. I was able to install curator. The problem was there were few other .list files present under sources.list.d. So it got fixed after deleting the other ones except curator.list.

Also I followed the instructions for delete_indices
here https://www.elastic.co/guide/en/elasticsearch/client/curator/5.0/ex_delete_indices.html & got to invoke curator process to delete indices which worked fine.

Now I have two questions.

First one is how do i define multiple filters to delete various indices in a single yml file ?

actions:
1:
action: delete_indices
description: >-
  Delete indices older than 10 days (based on index name), for logstash-
  prefixed indices. Ignore the error if the filter does not result in an
  actionable list of indices (ignore_empty_list) and exit cleanly.
options:
  ignore_empty_list: True
  disable_action: False
filters:
- filtertype: pattern
  kind: prefix
  value: nginx-access-
- filtertype: pattern
  kind: prefix
  value: nginx-error-
- filtertype: age
  source: name
  direction: older
  timestring: '%Y.%m.%d'
  unit: days
  unit_count: 10

I tried doing it like above but it did not work.

Second question is how do i setup cron for the action ? I tried invoking the below command but it did not work

curator --host localhost delete indices --older-than 60 --time-unit days --timestring '%Y.%m.%d'

Got the error

Error: no such option: --host

Please help me fix this

theuntergeek · May 29, 2017, 4:20pm

All of these questions are answered in the documentation.

Filters are joined together by logical AND operators, which is why your filters aren't working—nginx-access and nginx-error are mutually exclusive.

The second question indicates you read some blog somewhere and are getting outdated configuration information. Since v4.0, Curator switched to a YAML-based configuration. Curator 4.2 restored some of that older syntax in the form of singleton command line syntax, using curator_cli, rather than just curator.

Please check the documentation before you blindly accept instructions from an outdated blog. Check to see that the instructions are for the appropriate version, and perhaps verify that it is the same as the current documentation.

Thanks a lot @theuntergeek . There are a lot of outdated documentations which is the reason for confusion from my side. Also for configuring cron for delete indices , I have followed https://github.com/elastic/curator/issues/655 and added it in crontab. Is this the right way or is there any other yml based way cron can be configured ?

theuntergeek · May 30, 2017, 1:56pm

For a yaml installation, Curator is configured like:

1 1 * * * /path/to/curator --config /path/to/curator.yml /path/to/action.yml

This will run at 1:01am, and connect via the client configuration found in curator.yml and run the actions found in action.yml. Issue 655 addresses crontab issues for older versions of Curator, before v4.
