Inconsistent Metric Retrieval Across Multiple Services and Gaps in Monitoring

[al3v]

While using Cloud Eye Exporter to monitor multiple Huawei Cloud services, several metrics are not being retrieved properly. This issue is observed across various services, including RDS, ECS, and others. In addition, intermittent retrieval problems lead to potential gaps in monitoring.

Below are examples of RDS specific metrics that cause errors, as shown in the server.log screenshot provided below:

RDS Metrics

• rds039_disk_usage
• rds051_avg_disk_sec_per_read
• rds052_avg_disk_sec_per_write
• rds053_avg_disk_queue_length
• rds081_qps
• pg_dr_repl_stat
• pg_dr_wal_delay
• round_trip_time
• packet_loss_rate

Upon reviewing the (RDS API Reference), some of these metrics were not listed, suggesting they may no longer be supported. After removing these metrics from the exporter configuration, the related errors disappeared from the logs.

Questions

1. Has the current Cloud Eye Exporter code been updated to reflect the removal or deprecation of these metrics?
2. Could there be other reasons that might cause these error logs and resulting gaps in monitoring?
