Logging buffer sizes on ACE 4710

Answered Question
Sep 21st, 2009

Hi,

We are using Cisco ACE 4710 with the Admin and one other context defined.

We are both logging to syslog servers and to the local buffer for both contexts.

Currently only a few lines are logged in the Admin context buffer. When I issue a show logging command I get the following output:

ACE1/Admin# show logging

Syslog logging: enabled

Facility: 23

History logging: enabled (level- warnings)

Trap logging: enabled (level - information)

Timestamp logging: enabled

Fastpath logging: disabled

Persist logging: disabled

Standby logging: disabled

Rate-limit logging: disabled (min - 0 max 100000 msgs/sec)

Console logging: enabled (level - critical)

Monitor logging: enabled (level - warnings)

Logging to x.x.x.x udp/514

Logging to x.x.x.x udp/514

Device ID: hostname "ACE1"

Message logging:

Buffered logging: enabled (level - information) maximum size 4096

Buffer info: current size - 4096 global pool - 1048576 used pool - 1048576

min - 0 max - 4096

cur ptr = 2202 wrapped - yes

If I issue the same command in the other context I get the following information:

ACE1/CONTEXT# show logging

Syslog logging: enabled

Facility: 23

History logging: enabled (level- warnings)

Trap logging: enabled (level - information)

Timestamp logging: enabled

Fastpath logging: disabled

Persist logging: disabled

Standby logging: disabled

Rate-limit logging: disabled (min - 0 max 100000 msgs/sec)

Console logging: enabled (level - critical)

Monitor logging: enabled (level - warnings)

Logging to x.x.x.x udp/514

Logging to x.x.x.x udp/514

Device ID: hostname "ACE1"

Message logging:

Buffered logging: enabled (level - information) maximum size 1044480

Buffer info: current size - 1044480 global pool - 1048576 used pool - 1048576

min - 0 max - 1044480

cur ptr = 73251 wrapped - yes

It seems like the log buffer for the Admin context is only 4096 bytes and in the other context it is 1044480 bytes. Is there a way to specify the buffer size for the different contexts?

Thanks in advance for your help!

Best regards,

Harry

Harry,

the logging buffer is a resource.

Like all other resources, you can allocate a min and a max.

switch/Admin(config-resource)# limit-resource buffer syslog ?

minimum Set minimum limit
