2 Procol nd Prl Mtrics Strting in rvcntr 6.1 Bld28, th nccd cond lin utility supports gnrting trics for rvcntr Srvr s procol lyr nd Prl intrprtrs. Cling upon ths nw fturs producs fils in sprdsht fort (.csv) in /vr/opt/rvcntr/tbls/ tht cn b usd to look t th srvr s prfornc in ths rs. For xpl, running rcquus nd looking through th output y show you tht your srvr s procol lyr is fling bhind or is struggling to kp up. By thn running th ddd Procol-Mtrics you gt closr look into just how th procol lyr is doing with rspct to SMP nd ICMP oprts. Siilrly, intrrogt of your rcquus y b showing tht th Poll Mngr hrd or on of th hr thrds is hving troubl kping up. Running th nw Prl-Mtrics you gt glips into how th Prl intrprtrs r functing within you srvr. ogthr, ths two ddd functs provid dpr look into your srvr s procol lyr oprt nd Prl Intrprtr usg. Procol-Mtrics urning on procol-trics producs two csv fils tht r plcd in /vr/opt/rvcntr/tbls. 1) ProcolLyr-odMtrics.csv 2) ProcolLyr-PollMtrics.csv h contnts of ths fils r bsd on th nod count on your srvr nd th nubr of polls ctiv pr nod for th running instnc of ncsrvr. As such, ths fils cn gt firly lrg in siz nd contnt. o k viwing nd undrstnding th contnts of ths two fils bit sir, thr is Prl script in /opt/osinc/nc/bin/ cld procoltrics.pl tht cn b run ginst th csv fils to produc htl fils suitbl for viwing with wb browsr. Copy th procol-trics.pl fil into th /vr/opt/rvcntr/tbls/ dirctory nd xcut it dirctly fro thr using./procol-trics.pl to produc th htl fils for wb browsr viwing. o nbl th procol-trics vi th nccd cond lin utility, connct to your srvr nd issu on of th following conds. nccd> trc srvr procol-trics now (tks on-ti snpsh t this point in ti of th trics) nccd> trc srvr procol-trics on x (whr x rprsnts th nubr of inuts of how oftn you wnt th srvr to gnrt th tics. his ftur ovrwrits th two.csv fils t th slctd intrv. his ftur so nds to b turnd off using th trc srvr l off cond.) o turn off th trics nccd > trc srvr l off o chck th sttus of procol-trics nccd > trc srvr sttus l Convrting th csv output to htl hr is script loctd in /opt/osinc/nc/bin/ cld procol-trics.pl tht will convrt th csv fils into htl fils for sy viwing. h script nds to b run fro within th s dirctory s th ProcolLyr-Mtrics.csv fils (/vr/opt/rvcntr/tbls).
