Configuring asset polling
Asset polling allows you set the length of time between state change polling. To maximize the
efficiency of the polling feature (balancing the amount of possible information with any possible
performance impact), base your settings on the size of the SAN.
To configure asset polling, complete the following steps.
1. Select Server > Options.
The Options dialog box displays.
2. Select Memory Allocation in the Category list to set the memory allocation for the server and
client.
The Memory Allocation pane displays ( Figure 84 ).
3. Enter how often you want to check for state changes in the Check for state change every field.
This is the short tick interval which is used for adaptive asset collection (for more information,
refer to
“SAN data collection” on page 82). Valid values are from 1 through 600 seconds. You
cannot enter a value lower than the default minimum value.
Default minimum values are as follows:
•
Small/0–2000 ports (Professional): 60 seconds
•
Medium/2000–5000 ports: 120 seconds
•
Large/5000 or more ports: 180 seconds
4. Enter how often you want to check for state changes in the If no state change, Poll switch every
field.
This is the lazy polling interval which is used to schedule data collection when not triggered by
an event (for more information, refer to
“SAN data collection” on page 82). Valid values are
from 1 through 3,600 seconds. Default values are as follows:
•
Small/0–2000 ports (Professional): 120 seconds
