Get all active alarms using Lua

[Jason Eckelstafer]

I know the get_alarms utility only returns the first 500 records. Does anyone have the code for Lua to grab them all?

 

I found this topic that does it in perl and .net:  getting all alarms from NAS

 

I think the issue is that I'm not creating a session but haven't done that before.

Yes, this works in Lua like it does in the other languages. You do need a session to collect all of the alarms over the 500 limit. You start by creating a session with the nimbus.session_open() function. After that you use the nimbus.session_request() function instead of the nimbus.request() function, and you keep calling it as long as the return code is NIME_OK (0). Once you get back NIME_NOENT (4), then you're done. You can call the nimbus.session_close() function to close the session when done.

Thank you Keith! That worked perfectly. Here is the code I'm using to do this in case anyone else needs it:

 

--++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

--tdump(pTable)

-- This function is used to easily view the table structure found in Nimsoft

-- usage would be:  tdump(robot)

--++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

function tdump(t)

  local function dmp(t, l, k)

  if type(t) == "table" then

  print(string.format("%s%s:", string.rep(" ", l*2), tostring(k)))

  for k, v in pairs(t) do

  dmp(v, l+1, k)

  end

  else

  print(string.format("%s%s:%s", string.rep(" ", l*2), tostring(k), tostring(t)))

  end

  end

  dmp(t, 1, "root")

end

--end tdump(pTable)-----------------------------------------------------------------------------------

require (nsa_dir.."library\\uim_env_vars")

--above 'require' provides uimDomain, uimHub, uimServer, uimUser, uimPW, uimInstallLoc variables.

 

 

-- Log in to NimBUS. This is mandatory for most of the processes ran in this script.

nimbusLoginResult,nimbusLoginSID = nimbus.login(uimUser,uimPW)

 

 

pSessionHandle = nimbus.session_open("/"..uimDomain.."/"..uimHub.."/"..uimServer.."/nas")

 

 

args = pds.create()

pds.putInt(args, "show_all", 1)

 

 

local alarm_list_full = {}

local cycles          = 0

 

 

while true do

    local alarm_list_partial,rc = nimbus.session_request(pSessionHandle, "get_alarms", args)

    print("return code = "..rc)

 

 

    if rc == NIME_OK then

        for k,v in pairs(alarm_list_partial.alarms) do

            table.insert(alarm_list_full, v)

        end

    elseif rc == NIME_NOENT then

        print("All done in "..cycles.." requests")

        break

    else

        print("ERROR: Got rc = "..rc..", ending loop")

        break

    end

 

 

    cycles = cycles + 1

    if cycles > 100 then

        print("Too many cycles or A LOT of alarms, ending loop")

        break

    end

end

 

 

nimbus.session_close (pSessionHandle)

 

 

print("Total alarm count = "..#alarm_list_full)

 

 

tdump(alarm_list_full.alarms)
