pool check numeric values
Hello Community,
I'm trying to determine what each numeric value means when checking a pool's state.
ex)
3) iRule3->VS3:
when HTTP_REQUEST {
if { ([active_members pool1] < 1) or ([active_members pool2] < 1) or ([active_members pool3] < 1) } {
pool pool6
} else {
pool pool3
}
}
What does the " < 1 " actually mean? What other numeric values are there and what do they mean?
Thanks in advance.

- The example you show is checking the number of active pool members so <1 would mean all of the pool members are down.
- Would happen to know what the numbers below mean?
1, 2, 3, etc?
ex) Goal is to check if the pool member specified is flagged down/disabled or NOT
if { ([pool google-search member 192.168.254.189 80] < 1) } {pool google-search member 167.3.11.93 7800return} else {pool google-search member 167.3.10.93 7800return}Thanks.

If you want to check the status of a node you can use the LB::status command.

Your iRule would look something like this:when HTTP_REQUEST { log local0. "Node 1 Status: [LB::status pool my.pool.name member 10.10.10.10 80]" log local0. "Node 2 Status: [LB::status pool my.pool.name member 20.20.20.20 80]" if { [LB::status pool my.pool.name member 10.10.10.10 80] eq "down" } { HTTP::redirect "http://www.yahoo.com" } if { [LB::status pool my.pool.name member 20.20.20.20 80] eq "down" } { HTTP::redirect "http://www.msn.com" } }- Thanks! That works.
