Hello,

Is there a simple way to create alarm on specific robot using Lua script ?

Thank you,

Amit

Below is an example .Can be  executed directly from the nas -> Auto-Operator -> Scripts

-- create alarm

for i=1,10 do

nimbus.request("/<some_domain>/<some_hub>/<some_robot>/controller", "test_alarm", 2)

end

Hi,

Thanks, but this creates a test alarm.

I need to create an alarm where i can set the text...

Amit,

Hi Amit,

Here is a script that I've used in the past to create a completely new alarm building it from the pds.

Hope it helps!

cheers

Rowan

local a = alarm.get()

-- Generates a nimid

   key = ""

   base="ABCDEFGHIJKLMNOPQRSTUVWXYZ"

Hello Rowam,

Thank you very much.

But how do you use this ?

I tried running rawalarm ("mqilnxdvl",4,"Robot","Hello Robot") but i get an error :

Error in line 16: attempt to call global 'rawalarm' (a nil value)

Thanks,

Amit

Hi!

I am using the script below to generate new alarms
But it generates a new alarm for a single alarm based on the profile

How to modify it to generate a new alarm for any new alarm that hits the profile filter?

I believe you will have to replace the fixed variables with the environment variables that you reset by get alarm.

I believe you are correct, but I do not see fixed variables in the code

Say, what you want to do from start to finish. Do you really need this script?

Yes, I need

I have critical and major alarms which need to be updated by the team every X minutes

I thought about creating a new alarm from the old modifying part of the alarm message signaling that it is a renotification and deleting the old alarm

Repost did not work in my tests because I need to modify part of the alarm to inform the team that is a re-notification

Setting to send email from X to X minutes also does not work because it does not guarantee that it will be handled.

Amit

I've added a few extra default values, please give this a try now, it should work for you.

You will need to populate the devid and metid for the alarms to show in usm properly (against the device).

--local a = alarm.get()

-- Generates a nimid

function unique_id()

   key = ""

   base="ABCDEFGHIJKLMNOPQRSTUVWXYZ"

   math.random();math.random()

key = mid(base,math.random(1,26),1) .. mid(base,math.random(1,26),1) ..

sprintf("%07d", math.random(1,100000000)) .. "-" ..

sprintf("%05d",math.random(1,100000))

   return key

Thank you !

it works good !

Hi!

I don't think I'm following this script quite right.

When I enter an alarm ID into alarm.get I just get this result:

I thought it was supposed to rebuild the original alarm with the details taken from the ID entered into the alarm.get command?

Like this:

local a = alarm.get("AK45541189-22022")

What am I doing wrong?

Thanks,

Think I've found a solution to this..

--Gets alarm from AO

a = alarm.get()

--A business requirement of ours:

--Scans message and removes ampersands from message to allow alert to be passed to XML file

message1 = string.gsub(a.message, "%&","&amp;")

--Call library

require ("library/Create_alarm")

--Declare variables

alarm_domain = a.domain
alarm_origin = a.origin
robot_name = a.hostname
robot_source = a.source
probe_name = a.prid
alarm_SID = a.sid
alarm_severity = a.level
message = a.message
hub_name = a.hub

--optional variables

alarm_suppKey = supp_key

--Create Alarm

createAlarm (alarm_domain,alarm_origin,robot_name,robot_source,probe_name,alarm_SID,message1,alarm_severity,alarm_suppKey)

Hello,

How do I add the field (user_tag1)?

Thank you.

Hi,

Note :  ( Hubpost, post, post_raw are pretty similar ). I recommand to use post_raw.

If you take the code from Rowan it's : 

pds.putString (msg,"user_tag_1","here")

pds.putString (msg,"user_tag_2","here")

Best Regards,

Thomas

It worked...
I had adapted, but that's a lot better.
Thank you.

Hi!

I'm struggling to rebuild an alarm after passing it through a LUA script.  The aim is to remove and ampersands from the alert text and then rebuild the original alert, but with the new text.

If anyone could take a look I'd really appreciate it:

Rebuild alarm after processing through LUA 

Cheers,
