# Monitor Huawei Cloud with Nightingale

Scrape Cloud Eye (CES) metrics converted to Prometheus format by the cloudeye-exporter; templates cover ECS, RDS, DCS, ELB, Kafka, RocketMQ, CSS and WAF.

Last reviewed 2026-10-13

Huawei Cloud metrics come from the Cloud Eye service (CES). The `cloudeye-exporter` maintained by Huawei Cloud converts CES metrics per product namespace into Prometheus metrics named `huaweicloud_sys_<service>_<metric>`, which the Categraf `prometheus` input scrapes.

The templates are split by product: ECS hosts, RDS (MySQL and PostgreSQL), DCS Redis instances and proxy nodes, ELB, distributed messaging (Kafka, RabbitMQ, RocketMQ), Cloud Search (CSS/ES) and WAF, one dashboard each. The rules cover ECS CPU and memory, RDS connections and disk, DCS memory and hit ratio, ELB backend health; the metric reference explains each product's metrics one by one.

## What's in the template[​](#whats-in-the-template "Direct link to What's in the template")

* **14 dashboards**, 330 panels in total
* **35 alert rules**, each with runbook steps
* **286 metric descriptions**

## How to connect[​](#how-to-connect "Direct link to How to connect")

Deploy the [cloudeye-exporter](https://github.com/huaweicloud/cloudeye-exporter) and configure it with an IAM account's AK/SK, the project and the namespaces to collect. Once `http://<exporter>:8087/metrics?services=SYS.ECS` responds, scrape it per namespace with the Categraf `prometheus` input:

```
# conf/input.prometheus/huaweicloud.toml

interval = 120



[[instances]]

urls = ["http://<exporter>:8087/metrics?services=SYS.ECS,SYS.RDS,SYS.DCS,SYS.ELB"]

labels = { job = "huaweicloud" }
```

Cloud Eye metrics are at 60-second granularity or coarser, so do not collect more often than that.

1. Open the integration center in Nightingale, find Huawei Cloud, and [import the dashboards and alert rules](https://n9e.github.io/docs/data/integrations/import.md) into a business group.
2. Imported rules start disabled. [Check that the metrics are arriving](https://n9e.github.io/docs/data/integrations/verify.md) first, then enable the rules one by one with thresholds that fit your environment.

## Bundled alert rules[​](#bundled-alert-rules "Direct link to Bundled alert rules")

35 rules. Each lists its trigger condition (PromQL) and the steps to take when it fires. Thresholds are meant to be adjusted after import.

### Huawei Cloud ECS CPU usage exceeds 80%[​](#huawei-cloud-ecs-cpu-usage-exceeds-80 "Direct link to Huawei Cloud ECS CPU usage exceeds 80%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_cpu_usage >80
```

Runbook:

1. SSH in and use top -H to find the busiest processes and threads;
2. Use perf top or a language profiler to find the hot functions;
3. Tell business growth apart from a code fault (infinite loop, frequent GC);
4. For growth, change to a larger flavour in the console or scale out horizontally.

### Huawei Cloud ECS inode usage exceeds 80%[​](#huawei-cloud-ecs-inode-usage-exceeds-80 "Direct link to Huawei Cloud ECS inode usage exceeds 80%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_SlAsH_disk_inodesUsedPercent >80
```

Runbook:

1. Run df -i to find the mount point;
2. Count files level by level to find the directories with the most small files;
3. Common sources are log fragments, session files and container layers — confirm and bulk delete;
4. Longer term, consider moving small-file workloads to a dedicated partition.

### Huawei Cloud ECS NTP offset exceeds 1 second[​](#huawei-cloud-ecs-ntp-offset-exceeds-1-second "Direct link to Huawei Cloud ECS NTP offset exceeds 1 second")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_ntp_offset > 1000
```

Runbook:

1. Run chronyc tracking to check the offset and upstream source state;
2. Huawei Cloud ECS should use the internal NTP service (ntp.myhuaweicloud.com) — confirm it is configured;
3. Start chronyd if it is not running and enable it at boot;
4. For a large offset, use chronyc makestep to step the clock.

### Huawei Cloud ECS TIME\_WAIT connections exceed 20000[​](#huawei-cloud-ecs-time_wait-connections-exceed-20000 "Direct link to Huawei Cloud ECS TIME_WAIT connections exceed 20000")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_net_tcp_close > 20000
```

Runbook:

1. Run ss -s to see the real connection state distribution;
2. Run ss -tan | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -rn to find the peers;
3. The root cause is usually too many short-lived connections — switch the application to long-lived connections or a pool;
4. As an emergency measure enable net.ipv4.tcp\_tw\_reuse and widen ip\_local\_port\_range.

### Huawei Cloud ECS zombie processes above 0[​](#huawei-cloud-ecs-zombie-processes-above-0 "Direct link to Huawei Cloud ECS zombie processes above 0")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_proc_zombie_count >0
```

Runbook:

1. Run ps -ef | awk '$2 \~ /Z/ || $8 \~ /Z/' or ps aux | grep 'Z' to find the zombie processes and their parent PPIDs;
2. Once you have the parent, the problem is that it never calls wait() — this must be fixed in code;
3. As an emergency measure restart the parent so init reaps the zombies;
4. If the count keeps growing, the code fix is mandatory — restarting is only a stopgap.

### Huawei Cloud ECS available memory below 20%[​](#huawei-cloud-ecs-available-memory-below-20 "Direct link to Huawei Cloud ECS available memory below 20%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_mem_available < 20
```

Runbook:

1. Run free -h to check available memory and swap;
2. Run ps aux --sort=-%mem | head to find the largest consumer and judge whether it is leaking;
3. For a leak, capture a heap in the application — a restart alone is not enough;
4. For growth, change to a larger memory flavour in the console.

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_net_dropout > 50
```

Runbook:

1. Run ip -s link show to confirm TX dropped is growing;
2. Confirm whether the instance flavour's bandwidth cap is saturated — cloud bandwidth is capped per flavour and exceeding it drops packets;
3. If capped, adjust bandwidth or change the flavour in the console;
4. If not capped, check security groups, the kernel transmit queue and the application's send logic.

### Huawei Cloud ECS outbound packet error rate exceeds 50%[​](#huawei-cloud-ecs-outbound-packet-error-rate-exceeds-50 "Direct link to Huawei Cloud ECS outbound packet error rate exceeds 50%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_net_errout > 50
```

Runbook:

1. Run ip -s link show and ethtool -S to confirm the error counters;
2. In the cloud the physical layer is the provider's responsibility, so an abnormal error rate should go to a Huawei Cloud support ticket first;
3. At the same time confirm whether the instance flavour's bandwidth cap was exceeded;
4. If redundancy exists, move traffic away to stop the impact.

### Huawei Cloud ECS block device usage exceeds 80%[​](#huawei-cloud-ecs-block-device-usage-exceeds-80 "Direct link to Huawei Cloud ECS block device usage exceeds 80%")

```

Runbook:

1. Run df -h to find the mount point and du -x --max-depth=1 for the largest directories;
2. Clean logs and temporary files first, and use lsof +L1 for deleted-but-unreleased files;
3. Expand the EVS disk online in the console, then use growpart plus resize2fs/xfs\_growfs to grow the filesystem;
4. Longer term, evaluate moving the data directory to a dedicated cloud disk.

### Huawei Cloud ECS inbound packet loss rate exceeds 50%[​](#huawei-cloud-ecs-inbound-packet-loss-rate-exceeds-50 "Direct link to Huawei Cloud ECS inbound packet loss rate exceeds 50%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_net_dropin > 50
```

Runbook:

1. Run ip -s link show to confirm RX dropped is growing;
2. Confirm whether the instance flavour's bandwidth or PPS cap is saturated — cloud instances limit both;
3. If capped, adjust bandwidth or change the flavour in the console;
4. If not capped, raise the receive ring buffer with ethtool -G and consider enabling RPS.

### Huawei Cloud ECS inbound packet error rate exceeds 50%[​](#huawei-cloud-ecs-inbound-packet-error-rate-exceeds-50 "Direct link to Huawei Cloud ECS inbound packet error rate exceeds 50%")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_net_errin > 50
```

Runbook:

1. Run ip -s link show and ethtool -S to confirm the error counters;
2. In the cloud the physical layer is the provider's responsibility, so an abnormal error rate should go to a Huawei Cloud support ticket first;
3. At the same time confirm whether the flavour's bandwidth/PPS cap was exceeded;
4. If redundancy exists, move traffic away.

### Huawei Cloud ECS disk write IOPS too high[​](#huawei-cloud-ecs-disk-write-iops-too-high "Direct link to Huawei Cloud ECS disk write IOPS too high")

S2 Warning · for 1 min · Trigger:

```
huaweicloud_sys_agt_SlAsH_disk_agt_write_requests_rate > 99
```

Runbook:

1. Run iostat -x 1 to check actual IOPS and await;
2. Run iotop -oP to find the process writing the most;
3. Compare against the EVS disk type's IOPS ceiling to see whether it has topped out — ultra-high performance and general purpose disks differ greatly;
4. If it has, upgrade the disk type or expand it in the console (IOPS usually scales linearly with capacity); if not, optimise the application's write pattern.

### Huawei Cloud ECS disk read IOPS too high[​](#huawei-cloud-ecs-disk-read-iops-too-high "Direct link to Huawei Cloud ECS disk read IOPS too high")

S2 Warning · for 1 min · Trigger:

```

Runbook:

1. Confirm the instance and broker state in the Huawei Cloud console;
2. Confirm clients have failed over to other brokers — with multiple brokers only some partitions are unavailable;
3. If the console looks fine but clients report errors, check the network and security groups plus the client's nameserver address;
4. If it stays unavailable, open a ticket with Huawei Cloud.

### RocketMQ per-core CPU load exceeds 1.5[​](#rocketmq-per-core-cpu-load-exceeds-15 "Direct link to RocketMQ per-core CPU load exceeds 1.5")

S1 Critical · for 3 min · Trigger:

```
huaweicloud_sys_dms_broker_cpu_core_load > 1.5
```

Runbook:

1. Check that broker's TPS and message backlog curves in the console to tell producer-side from consumer-side pressure;
2. For a heavy consume backlog, scale out consumers first;
3. For a produce spike, evaluate upgrading the instance flavour;
4. Confirm no oversized messages or huge batch sends are overwhelming the broker.

### RocketMQ memory usage exceeds 85%[​](#rocketmq-memory-usage-exceeds-85 "Direct link to RocketMQ memory usage exceeds 85%")

S1 Critical · for 3 min · Trigger:

```
huaweicloud_sys_dms_broker_memory_usage > 85
