Is there a way to specify multiple collection Rules or we can specify only one rule?

{
  "Egress": {
    "S3Storage": {
      "monitorS3Blob": {
        "bucketName": "xxx",
        "accessKeyId": "xxx",
        "secretAccessKey": "xxx",
        "regionName": "ap-south-1"
      }
    }
  },
  "CollectionRules": {
    "HighCpuRule": {
      "Trigger": {
        "Type": "EventCounter",
        "Settings": {
          "ProviderName": "System.Runtime",
          "CounterName": "cpu-usage",
          "GreaterThan": 1,
          "SlidingWindowDuration": "00:00:05"
        }
      },
      "Actions": [
        {
          "Type": "CollectGCDump",
          "Settings": {
            "Egress": "monitorS3Blob"
          }
        },
        {
          "Type": "CollectTrace",
          "Settings": {
            "Profile": "Cpu",
            "Duration": "00:01:00",
            "Egress": "monitorS3Blob"
          }
        }
      ],
      "Limits": {
        "ActionCount": 2,
        "ActionCountSlidingWindowDuration": "1:00:00"
      }
    }
  }
}

currently, I have configured one collection rule named HigCPURule can I specify more rules or only one rule?

Yes, the CollectionRules section is a mapping of names to collection rule options; see the JSON Schema for CollectionRules: https://github.com/dotnet/dotnet-monitor/blob/main/documentation/schema.json#L30

{
  "CollectionRules": {
    "Rule1": { ... },
    "Rule2": { ... },
    "Rule3": { ... },
    ...
  }
}
