kill 慢查詢腳本 -MongoDB

很多時(shí)候,有些慢查詢導(dǎo)致MongoDB壓力很大, 花了點(diǎn)時(shí)間寫了個(gè)腳本循環(huán)kill些慢查詢操作.  

1.2.var j=0; 
3.
•var _DEF_TIME=10; //設(shè)置慢查詢時(shí)間  
•for (var i in db.currentOP().inprog) {  •    var op = "";  •    var opid; 
•    var memProg={} 
•    if (typeof(undefined) == typeof(db.currentOP().inprog[i])) {  •        continue;  •    } 
•    memProg=db.currentOP().inprog[i]; 
•    op = memProg.op; 
•    opid = memProg.opid; 
•    print(i); 
•    if (op=="query") {  •        if (memProg.hasOwnProperty('secs_running')) {  •            var useTime  = memProg.secs_running; 
•            if (useTime >= _DEF_TIME) {  •                db.killOp(opid); 
•                j++; 
•                print("killed "+j+" Query Operation!");  •            } 
•        } 
•    } 
•}
