Get all active alarms using Lua

  • 1.  Get all active alarms using Lua

    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)-----------------------------------------------------------------------------------

    ------------------------------------------------------------------------------------------------------

     

     

    nsa_dir="E:\\Program Files (x86)\\Nimsoft\\sdk\\nsa\\"

     

     

    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)
