Customizing Helper Strings for Dependency Processing

Zone names are set by the Storage Administrator and typically include the names of devices connected to ports. The dependency processing algorithm processes the zone name strings using various helper strings to identify the possible host names associated with a port. A DNS lookup is performed on the possible names to identify the most likely host FQDN. You can customize the helper stringers for your environment and improve the accuracy of the inferred hosts.

1
On the Storage Environment dashboard, in the Administration tab, click Review Physical Host FQDNs.
2
Click Change Zone Processing Params.
3
To specify IP addresses to ignore during dependency processing, click Invalid IPs. Click Add, specify an IP address, and click Add.
Some DNS setups always return a default IP address when a DNS lookup of a possible host name fails. If a DNS lookup of a host name returns an IP address listed in the Invalid IP table, the host name is considered invalid for dependency processing purposes.
5
To specify strings used as separators for readability in the zone names, click Split Strings. Click Add, specify a string, and click Add.
6
To specify strings that you want to convert to other strings before performing a host name DNS lookup, click Translation Strings. Click Add, specify a string found in the zone information and the new string to use, and click Add.

Reviewing Inferred Hosts

You can see a list of inferred hosts on the Infrastructure dashboard. From this dashboard, you can explore hosts and change their host port assignments if necessary. If you are interested in monitoring and collecting detailed data about an inferred host, you can set up an agent to monitor the host. This action moves the host from the inferred list to the appropriate monitored host list.

For more information about the Infrastructure dashboard, see the Managing the Infrastructure Cartridge section of the Foglight for Storage Management online help.

5
Click the SAN Topology tab.
6
Click a Cloud icon to show the connections through a port in a Details window.
7
If the assigned host is incorrect, click the Host Port icon and select the desired action, such as Assign to Different Host or Remove Link to Host.
NOTE: If your user credentials do not include the role Administrator, you need to ask someone with this role to create an agent to monitor the host.
10
Click Configure Host Monitoring.
For help with the wizard, see “Adding a Monitored Host” in the Managing the Infrastructure Cartridge section of the Foglight for Storage Management online help.

Modifying Data Collection Schedules

Generally speaking, the default data collection schedules are suitable for most environments. If you notice that some agents take an extended time to collect topology data or performance data, and modifying your monitoring environment is not a suitable solution, you may want to change the data collection schedules for the affected agents. You can find the current duration of collections in the Edit Agent Properties dialog box.

Understanding Data Collection Types and Schedules

Storage Collector agents perform two types of collections: topology collections and performance collections.
