Load balancing monitoring

As an important part of the infrastructure, monitoring and alarm are very important for daily operation and maintenance. It provides load balancing monitoring function to help users quickly understand the running status of load balancing. There are 8 monitoring indicators for monitoring, including real-time bandwidth, total connections, and http status code. It also supports user-defined alarm rules.

Layer 4/7 monitoring public monitoring items:

Monitoring items specific to Layer 7 monitoring:

be careful:

The total number of connections and the number of new connections refer to the number of connections from the client to the load balancer; The total number of connections consists of the number of established connections, the number of non established connections and the number of other connections. The number of other connections is very small and is generally ignored.

Alarm description

When the load balancing is in an unhealthy state, an alarm event will be triggered and the alarm event contact will be notified. Alarm events are triggered by user-defined alarm rules.

Alarm rules

Alarm rules are mainly composed of associated resources, rule descriptions and notification methods.

Rule description Including statistical cycle, statistical method, condition judgment, and threshold.

• Monitoring sub items: monitoring page monitoring items, which are broken down to each sub item. For example, the monitoring item "bandwidth" includes "inflow bandwidth" and "outflow bandwidth";
• Statistical Cycle: check the events that occur in unit time cycle;
• Statistical method: according to the average value, maximum value and minimum value;
• Threshold value: the threshold value of the event. If the threshold value is exceeded, the alarm event will be triggered.

be careful:

The monitoring alarm rules are set for Layer 4 ports (TCP/UDP), Layer 7 ports (HTTP/HTTPS), or all ports. All ports are the total data of all front-end ports of the load balancing instance. In principle, Layer 4 ports correspond to Layer 4 alarm rules, and Layer 7 ports correspond to Layer 7 alarm rules. Layer 7 alarm rules can be selected for Layer 4 ports, but they do not take effect. vice versa.
