You can use client IP filters to choose the networks that you want to monitor. By applying filters, administrators can limit the scope of the monitored computers. By default, only localhost is monitored. If the IP filter list is empty, all IP addresses are monitored. Any IP addresses that fit the filter definitions are excluded from client-side monitoring.

The following examples show how to use IP filters to monitor IP addresses.

Exclude a Set of IP Addresses from Monitoring

Example: To monitor all IP addresses except 192.168.*.*

  1. To monitor all IP addresses, except some (IP addresses 192.168.*.* in this example), on the Client Side Configuration tab, in the Configure client IP filter section, click Add.

  2. On the Client IP address filter page, set the Comparison Type to IP is in subnet.

    Note

    Comparison type has two values: In subnet excludes user IP addresses that match the IP addresses in the subnet. Not in subnet excludes the user IP addresses that do not match the IP addresses in the subnet.

  3. In the IP address box, enter the IP addresses that you want to exclude from monitoring. In this example, enter 192.168.0.0.

  4. In the Netmask box, enter the part of the filter IP address and user IP address that have to be compared for equality. In this example, enter 255.255.0.0.

  5. Click OK.

Monitor a Specific Set of IP Addresses

Example: To monitor the specific set IP addresses 192.168.*.*

  1. To monitor a specific set of IP addresses (in this example, IP addresses 192.168.*.*), on the Client Side Configuration tab, in the Configure client IP filter section, click Add.

  2. On the Client IP address filter page, set the Comparison Type to IP is not in subnet.

  3. In the IP address box, enter the IP addresses that you want to monitor. In this example, enter 192.168.0.0.

  4. In the Netmask box, enter the part of the filter IP address and user IP address that have to be compared for equality. In this example, enter 255.255.0.0.

  5. Click OK.

Monitor a Specific Set of IP Addresses and Exclude Some IP Addresses from that Set

Example: To monitor IP addresses 192.168.*.* and exclude IP addresses 192.168.10.*

  1. To monitor a specific set of IP addresses and exclude some from that set (in this example, only IP addresses 192.168.*.*, except IP addresses 192.168.10.*), you have to configure two filters. First, create the filter to scope to only IP addresses 192.168.*.*, and then a filter that excludes 192.168.10.*. To create the first filter to monitor only IP addresses 192.168.*.*, on the Client Side Configuration tab, in the Configure client IP filter section, click Add.

  2. Set the Compare Type to IP is not in subnet.

  3. In the IP address box, enter the IP addresses that you want to monitor. In this example, enter 192.168.0.0.

  4. In the Netmask box, enter the part of the filter IP address and user IP address that have to be compared for equality. In this example, enter 255.255.0.0.

  5. Click OK.

  6. Then, create the second IP filter to exclude IP addresses 192.168.10.*. On the Client Side Configuration tab, in the Configure client IP filter section, click Add.

  7. Set the Compare Type to IP is in subnet.

  8. In the IP address box, enter the IP addresses that you want to exclude from monitoring. In this example, enter 192.168.10.0.

  9. In the Netmask box, enter the part of the filter IP address and user IP address that have to be compared for equality. In this example, enter 255.255.255.0.

  10. Click OK.

When to Use the IPv4 and IPv6 Filters

If the IPv4 protocol is the only protocol that is enabled on the web server, leave the Use IPv6 check box blank.

If the IPv6 protocol is enabled on the web server, select the Use IPv6 check box to add the IPv6 filter.
