JS脚本强制KILLOP解决MONGODB查询慢的问题

作者：袖梨 2022-06-29

很多时候,有些慢查询导致MongoDB压力很大, 花了点时间写了个脚本循环kill些慢查询操作

代码如下

复制代码

var j = 0;
var _DEF_TIME = 10; //设置慢查询时间
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!");
            }
        }
    }
}

运行方式:

./mongo 10.15.107.154:30000 < ./Self-Script/killSlow.JS
