Poller sending duplicate events to the primary

If your poller is sending duplicate events to the primary make sure that your EventActions.json script does not have any 'or' gates in your 'IF' statements - 'AND' and 'and' are fully supported, but 'or' (also 'OR') is not supported and can lead to unexpected behavior.

It's also best practice to use "BREAK" : "true" whenever possible, for example:
If we confirm that event.event = 'Node Down' there's no need to also check to see if event.event = 'Interface Down' etc.


Fast create remote event

We have recently rewritten create remote event in Go and have provided the option to use token auth skipping out one of the auth requests from the old Perl version.

...

We have retained all arguments from the perl version.

Version 1.1.0 .1 can be downloaded here: https://dl-omk.opmantek.com/remote_event/fast-remote-event-1.1.0-Linux-x86_64.bin

Code Block
  -d int
    	Log Level (default 4)
  -p string
    	Password for the remote user
  -path string
    	Path for generate auth token script (default "/usr/local/omk/bin/generate_auth_token.pl")
  -q	DontQuiet level, (1|true|0|false).  Don't output anything (default true), -q=0 to see event id of remote system.
  -retry int
    	Maximum number of retries
  -s string
    	http://servername:portnumber/omk, API endpoint details are automatic. (default "http://localhost:8042/omk")
  -t string
    	Token for auth
  -u string
    	Username for remote server (default "nmis")
  -v	Verify the servers TLs connection (default true)
  -version
    	Print out the version

...

If your Opmantek Applications in a non standard location you can use -path to point to the full path of generate_auth_token.pl which is shiped in /usr/local/omk/bin/generate_auth_token.pl in future versions we aim to remove this.


Debug Values

to see debug set value to one i.e. -d 1, debug comes in as stdout (standard output)

Boolean Values

for the TLS verify command we support the following flags

1, 0, t, f, T, F, true, false, TRUE, FALSE, True, False


Retries

Sometimes the end server is busy but using the flag -retry you can instruct the http handler to make X amount of requests to try again, this will perform a back off to try and not swamp the end server.
