Centralized Logging Example
This section provides an example of log aggregation when a custom_logger and an fbl module are defined.
The following is an example configuration for the custom_logger module:
custom_logger "custom_logger1" { permanent_failure_logfile = "cluster:///var/log/ecelerity/custombounce.cluster=>master" permanent_failure_format = "%t@%i@%BI@%CI@B@%r@%R@%m@%M@%g@%b@%c@%C@%B@%H@%h{X-campaignid} » @%h{date}@%h{subject}@%n" transient_failure_logfile = "cluster:///var/log/ecelerity/custombounce.cluster=>master" transient_failure_format = "%t@%i@%BI@%CI@T@%r@%R@%m@%M@%g@%b@%c@%C@%B@%H@%h{X-campaignid} » @%h{date}@%h{subject}@%n" }
Note: The format options in the custom_logger module above should be unbroken in your configuration file.
The following is an example configuration for the fbl module:
fbl { Auto_Log = true # default is "false" Log_Path = "cluster:///var/log/ecelerity/fbllog.cluster=>master" Addresses = ( “^.*@fbl.domain.com” ) # default is unset Header_Name = “X-MSFBL” # this is the default User_String = “%{vctx_mess:my_context_variable}” # default is unset Message_Disposition = “blackhole” # default is blackhole, also allowed to set to "pass" Condition = “can_relay” # default is unset, should be name of a vctx entry }
Given the above configuration for the custom_logger module and the fbl module, you would configure the cluster logs in the following way:
cluster { cluster_group = ec_cluster control_group = ec_console logs = [ rejectlog = "/var/log/ecelerity/rejectlog.cluster" paniclog = "/var/log/ecelerity/paniclog.cluster" mainlog = "/var/log/ecelerity/mainlog.cluster" acctlog = "/var/log/ecelerity/acctlog.cluster" bouncelog = "/var/log/ecelerity/bouncelog.cluster" fbllog = "/var/log/ecelerity/fbllog.cluster" custombounce = "/var/log/ecelerity/custombounce.cluster" ] ... }
If the logfile
option in the Logs
scope is configured as shown in “eccluster.conf
File”, you will have access to the fbl logs of node1
belonging to subcluster mysubcluster
in the /var/log/eccluster/year/mon/day
/fbllog/mycluster/node1 directory on the log aggregator.
