Health checks
Health checks
The following are objects to check on the health of a server. The ServerIron automatically uses a
Layer 3 ping to check a server’s health. Ping is enabled by default and cannot be disabled.
Real server objects
A real server is an application server which is load-balanced by the Server Load Balancing (SLB)
switch.
NOTES: The following tables have been replaced:
Name, OID, and Syntax Access Description
snL4PolicyPortAccessTable
brcdIp.1.1.4.12.1
None The IP Layer 4 Policy Interface (Port) Access Table.
snL4PolicyPortAccessEntry
brcdIp.1.1.4.12.1.1
None An entry in the table.
snL4PolicyPortAccessPort
brcdIp.1.1.4.12.1.1.1
Syntax: Integer
Read only The IP interface (port) to which the Layer 4 policy applies.
snL4PolicyPortAccessList
brcdIp.1.1.4.12.1.1.2
Syntax: OctetString
Read-write This list consists of the policies configured in
“snL4PolicyTable”. Each octet in the list contains a valid ID
number (“snL4PolicyId”) that identifies a policy in the
snL4PolicyTable. That policy must have been created prior to
the using this object.
Valid values: 1 – 64 octets
snL4PolicyPortAccessRowStatus
brcdIp.1.1.4.12.1.1.3
Syntax: Integer
Read-write Controls the management of the table rows. The values that
can be written are:
• delete(3) – Delete the row
• create(4) – Create a new row
• modify(5) – Modify an existing row
If the row exists, then a SET with a value of create(4) returns a
"bad value" error. Deleted rows are removed from the table
immediately.
The following values can be returned on reads:
• noSuch(0) – No such row
• invalid(1) – Row is inoperative
• valid(2) – Row exists and is valid
snL4PingInterval
brcdIp.1.1.4.1.26
Syntax: Integer
Read-write Shows how often the ServerIron sends a Layer 3 IP ping to test the basic
health and reachability of the real servers. This object allows you to
change the interval between the ping packets.
Valid values: 1 – 10 seconds
Default: 2 seconds
snL4PingRetry
brcdIp.1.1.4.1.27
Syntax: Integer
Read-write Shows the number of times the ServerIron resends a ping to a real
server that is not responding before the server fails the health check.
Valid values: 2 – 10 tries
Default: 4 tries
