如果出现在输出中(检查 -> 输出)，我需要计算 WARNING 和 CRITICAL 出现的次数。
如果这是一个新手问题，请原谅。我对此很陌生。
最佳答案
你可以这样做:
let critialCount = 0
let warningCount = 0
for(let i = 0; i < data.length; i++) {
if(data[i].check.output.indexOf('CRITICAL') > -1) {
critialCount++
}
else if(data[i].check.output.indexOf('WARNING') > -1) {
warningCount++
}
}
console.log('Critical count: ' + critialCount)
console.log('Warning count: ' + warningCount)
