Basic usage

okerrupdate utility

okerrupdate is small script which updates/creates indicators in okerr project.

This will create simplest indicator 'myindicator' with all default settings (type 'heartbeat', policy 'Default'). Indicator will send alert if it will be updated to 'ERR' or if will not be updated for some time (Default policy period+patience).

$ okerrupdate myindicator OK
okerr updated (200 OK) myindicator@okerr = OK

This will create numerical indicator 'temp' with current value 36.6, and policy 'Daily'. Will send alert if not updated for a day or if value will be over maxlim (37).

$ okerrupdate -p Daily -m 'numerical|maxlim=37' temp 36.6
okerr updated (200 OK) temp@okerr = 36.6

Project TextID and secret is read from /etc/okerr/okerrupdate file or OKERR_TEXTID and OKERR_SECRET environment variables.

okerrmod utility

okerrmod is script to use different okerr checks. After initial okerrmod --init, few basic simple check modules are enabled.

List all available check modules:

$ okerrmod --list
+ backups 0.1 Check freshness for backup files
+ df 0.1 Free disk space
...

To run enabled checks just run okerrmod without any other commands:

xenon@braconnier:~$ sudo okerrmod 
okerr updated (200 OK) braconnier:maxfilesz@okerr = 9077814
okerr updated (200 OK) braconnier:apache@okerr = 0
okerr updated (200 OK) braconnier:nonempty@okerr = 0
okerr updated (200 OK) braconnier:empty@okerr = 0
...

To run just one check:

$ sudo okerrmod --run ok
okerr updated (200 OK) braconnier:ok@okerr = OK

To enable new check:

$ sudo okerrmod --enable sql
2020/01/17 18:46:58 enable /home/xenon/repo/okerrupdate/okerrupdate/mods-available/sql

After this, you may want to edit default configuration for this check

sudo vim /etc/okerr/mods-env/sql

After this, okerrmod will run this check.

To create your own very basic check 'my' create dir /etc/okerr/mods-available/my and edit /etc/okerr/mods-available/my/check:

#!/usr/bin/python3
print("STATUS: OK")

or if you prefer shell (check is any executable file):

#!/bin/sh
echo STATUS: OK

Now you can run it manually okerrmod --run my, enable okerrmod --enable my, make/edit config file for it /etc/okerr/mods-env/my.

Using okerrupdate python library

Simplest case:

#!/usr/bin/python
import okerrupdate

op = okerrupdate.OkerrProject('MyTextID', secret='MySecret')
i = op.indicator('temp', method='numerical|maxlim=37', policy='Daily')
i.update('36.6')
