Hello fahmi,

1-) log in your RNC/BSC and you can find them under( /bam/common/fam/famlogfmt ) for CHR and you have a folder named PCHR for the second.
2-) CHR = call history records(measures all the calls), PCHR = performance call history records (measures the failures, till RAN14 where you can change a switch for PCHR to measure both, call and failures).
3-) PCHR is used for investigation
4-) FMA is your choice and you can find it for free on this forum. UMTS FMA 3.8.1 or the 3.8.2 version.

This was for Huawei.

Hope it helped and don't forget to rep as I am near Senior member :D
