In the Central list, select
Monitoring Server Groups.
Click the New Monitoring Server Group
Server / Monitor wizard appears.
- Select Monitoring Server Group and click Next. The Name and Connection step is shown.
Type a name for the Monitoring Server
and optionally provide a description. Finally type the hostname or IP address of the
device into the Host field and click Next.
The Resources step is shown. Check
Network Devices and click Next. The
Hosts/Device Agents screen appears.
Note: Use the IP address of the physical device when setting up monitoring for a network device .
Enter the SNMP port number and community
string. The SNMP Community string works like a user id or password and allows access to a
router's or other device's statistics.
Connection. If the connection is successful, you will see a pop-up
containing some information about the device. If the connection fails, you will see an
error message explaining what went wrong.
- Click Next.
Review the information to be sure it is
correct, then check the Create a new Monitor for this Monitor
Server box and click Finish.
- Enter a name for the Monitor and an optional description, then click Next.
Now, choose the statistics you want to
monitor. For each statistic, you can choose a sample rate that determines how often that
statistic will be collected.
- In addition to the standard
statistics that are offered (for example, "Mbits Received"), you can track the value
of any SNMP gauge or counter. For example, to track the number of IP datagrams
discarded due to an invalid address, check the "Counter" box, and enter
126.96.36.199.188.8.131.52.0in the "Arguments" column.
- A counter describes a continually increasing value. For example, many SNMP-enabled devices represent the number of bytes received as a counter of the total number since the device was started. When you add a counter to the SNMP monitor, CloudTest will take two samples and return the difference.
- A gauge describes an "instant" value. For example, the current size of the outbound packet queue is usually a gauge. When you add a gauge to the SNMP monitor, CloudTest will simply record the sampled value.
- You can use the "Add Custom Object" button to add as many SNMP counters or gauges as you like. Some more examples:
To track the number of SNMP GET requests, check the "Counter" box and enter
184.108.40.206.220.127.116.11.0in the "Arguments" column.
To track the current number of open TCP connections, check the "Gauge" box and enter
18.104.22.168.22.214.171.124.0in the "Arguments" column.
- In addition to the standard statistics that are offered (for example, "Mbits Received"), you can track the value of any SNMP gauge or counter. For example, to track the number of IP datagrams discarded due to an invalid address, check the "Counter" box, and enter
- When you are finished, click Next.
