The network monitoring module of Cloud Managed Network monitors various resources, including network devices, servers, leased lines, and application network probes. The module uses protocols such as PING, SNMP, and HTTP to provide features such as data collection, data parsing, anomaly alerts, and data dashboards. The module also supports probing of IPv6 addresses. To monitor your infrastructure, such as network devices, leased lines, and servers, with Cloud Managed Network, you must first create a custom monitoring item.
Prerequisites
Procedure
Log on to the Cloud Managed Network console.
In the navigation pane on the left, click Network Monitoring > Monitoring Item Management.
Above the list, click the Create Monitoring Item button, and then select Create Custom Monitoring Item.
On the Create Custom Monitoring Item page, select the desired monitoring item type.
Click the Create button. In the dialog box that appears, enter the basic information for the monitoring item, including its name, description, and collection probe.
Each monitoring type requires specific information. For more information, see the following sections.
Click Next to edit the parsing code. For most monitoring types, Cloud Managed Network provides default parsing code that you do not need to modify. If you have specific requirements, you can modify the code according to the parsing code specifications.
Optional: Click Next to set alert rules. To add an alert rule for the collected data, click Add Alert Rule. Then, enter or select the Alert Status, Metric Name, Expression, and Comparison Value for the rule.
Click OK to save the monitoring item.
PING monitoring
Complete Steps 1 to 5 in the procedure above.
Select the number of packets to send and the packet interval in milliseconds (ms) for PING monitoring. The recommended setting is 30 packets per minute at an interval of 1000 ms.
Select the device type: Network Device, Server, or IoT Device.
For leased line PING monitoring, select whether to probe the local IP or the peer IP.
SNMP monitoring
Complete Steps 1 to 5 in the procedure above.
Select the device type: Network Device, Server, or IoT Device.
Select the SNMP collection type: get, getNext, getBulk, getWalk, or snmpwalk. The recommended type is snmpwalk.
Server monitoring
Complete Steps 1 to 5 in the procedure above.
For process monitoring, enter a process keyword, such as `redis`, and any optional startup parameters for the process.
For script monitoring, enter the script path and parameters, such as `/home/admin/example.sh parameter1 parameter2`.
Application network probe monitoring
Complete Steps 1 to 5 in the procedure above.
For HTTP service monitoring, enter one or more domain names to monitor, such as `www.example.com`.
For TCP PING and UDP PING monitoring, enter one or more IP addresses and ports to monitor.
For API monitoring, enter one or more domain names to monitor. You can also specify the HTTP API request method (GET or POST) and the POST body, such as `{"exampleKey":"exampleValue"}`.
PING monitoring and PING IPv6 monitoring perform ICMP checks on IPv4 and IPv6 addresses, respectively. Select the number of packets to send and the packet interval in milliseconds (ms). The recommended setting is 30 packets per minute at an interval of 1000 ms.
For MTR diagnostics, you can set a target domain name or IP address and a specific port. This feature uses the MTR tool to perform network troubleshooting.
