You can display the following types of Solace PubSub+ event broker logs:
You can also clear ACL, no-subscription-match, or REST logs:
ACL Logs
Access control lists (ACLs) are used to manage clients’ access to the Solace PubSub+ event broker and the topics to which they are permitted to publish and subscribe. For more information, refer to Controlling Which Topics a Client May Publish and Subscribe To.
ACL logs are not maintained after an event broker restarts.
To display the most recent 1,000 ACL log entries, enter the following User EXEC command:
solace> show log acl [client-connect | publish-topic | subscribe-topic] [client-username <username>] [message-vpn <vpn-name>] [wide]
Where:
client-connect shows only logs relating to client-connect ACLs.
publish-topic shows only logs relating to publish-topic ACLs.
subscribe-topic shows only logs relating to subscribe-topic ACLs.
client-username <username> specifies the client username. This value may contain wildcards.
message-vpn <vpn-name> is the Message VPN name. The wildcards * or ? may be used.
wide generates the output log in a wide format.
Command Logs
Command logs capture information about Solace PubSub+ event broker commands issued by users. For more information, refer to Monitoring Events Using Syslog.
To display access user command logs, enter the following User EXEC command:
solace> show log command [lines <num-lines>] [find <search-string>]
Where:
lines <num-lines> specifies the number of lines to read. The default is 1000.
find <search-string> specifies a string to use as a filter. No filtering is applied by default.
Event Logs
To display Solace PubSub+ event broker event logs, enter the following User EXEC command:
solace> show log event [lines <num-lines>] [find <search-string>]
Where:
lines <num-lines> specifies the number of lines to read. The default is 1000.
find <search-string> specifies a string to use as a filter. No filtering is applied by default.
System Logs
System logs are a subset of event broker event logs that are duplicated into system.log. This provides a method for logging important system events in high‑event environments. The Syslog Event Reference specifies which events are duplicated into system.log.
To display Solace PubSub+ event broker system logs, enter the following User EXEC command:
solace> show log system [lines <num-lines>] [find <search-string>]
Where:
lines <num-lines> specifies the number of lines to read. The default is 1000.
find <search-string> specifies a string to use as a filter. No filtering is applied by default.
No-Subscription-Match Logs
When a client publishes Direct or Guaranteed messages, a no-subscription-match statistic is logged for each message that doesn't match a topic subscription.
Messages that match a configured sequenced topic aren't recorded as a no-subscription-match even if they don't match a subscription. All other messages that don't match subscriptions are logged, including messages that only match a replicated topic subscription.
To display the most recent 1000 no-subscription-match logs, enter the following User EXEC command:
solace> show log no-subscription-match [client-username <username>][client-name <name>] [message-vpn <vpn-name>] [wide]
Where:
client-username <username> specifies show only logs for the given client username. A username can contain up to 189 printable ASCII characters (that is, characters in the range 0x20 – 0x7e) and is case-sensitive. The provided username may contain the wildcards * or ?.
client-name <name> specifies to show only logs for a client matching the given name.
message-vpn <vpn-name> is the Message VPN name.
wide outputs the log in a wide format.
no-subscription-matchlogs aren't maintained after an event broker restarts.- For a username, client name, or Message VPN name, you can enter a full name, or part of a name, with either the wildcard character
?used to represent one character of the name, or the wildcard character*used to represent zero or more characters of the name, where entering only the wildcard character*for the name displays all clients.
REST Logs
To display Solace PubSub+ event broker REST logs, enter the following User EXEC command:
solace> show log rest [rest-delivery-point] [errors] [wide]
Where:
rest-delivery-point show logs for REST Delivery Points.
errors show logs for error responses.
wide outputs the log in a wide format.
Clearing Event Broker Logs
To clear ACL, no-subscription-match, or REST logs, enter the following Privileged EXEC command:
solace# clear log [acl][no-subscription-match][rest]
Where:
acl clears the current ACL log entries
no-subscription-match clears any no-subscription-match log entries
rest clears REST log entries
