There is also for Siemens:
TACCBPRO Total number of accesses by procedures (PCH, AGCH)
NACSUCPR Number of accesses with a successful result by procedure (PCH,AGCH and RACH)
SBS Counter:
SDCCH Congestions for Immediate Assignment Messages
IMM. ASS CMD (Abis Interface)(including those IMM. ASS. CMD. messages thatcontain an IMM. ASS. REJ. message) = TACCBPRO
IMM. ASS CMD / IMM. ASS. REJ. (Um Interface)(difference between IMM. ASS.CMD and Del. Ind.,including those IMM. ASS. CMD. messages thatcontain an IMM. ASS. REJ. message) = NACSUCPR
If there are number of immediate assignments by BSC procedure then look for number of AGCH losses (TACCBPRO) measured against immediate assignment commands sent to MS via AGCH (NACSUCPR) to identify number of Immediate Assignments without MS Seizure.
