The command you provided is using the AWS Command Line Interface (CLI) to retrieve log entries from AWS CloudWatch Logs based on certain criteria. Here's a breakdown of the command:
-
awslogs
: This is the AWS CLI command to interact with CloudWatch Logs. -
get
: This is the specific action within theawslogs
command to retrieve log entries. -
${-var-log-syslog}
: This is a placeholder for the log group name or log stream name. The actual value is not provided in the command you shared. You would need to replace${-var-log-syslog}
with the desired log group or log stream name. -
--start='${2h ago}'
: This parameter specifies the start time for log retrieval. In this case, it is set to two hours ago. It uses the${2h ago}
syntax to indicate a relative time. This means it will retrieve logs starting from two hours ago until the end time specified. -
--end='${1h ago}'
: This parameter specifies the end time for log retrieval. In this case, it is set to one hour ago. Similar to the start time, it uses the${1h ago}
syntax to indicate a relative time.
To use this command, you need to replace ${-var-log-syslog}
with the desired log group or log stream. For example, if you wanted to retrieve logs from a log group named "my-log-group", the command would be:
awslogs get my-log-group --start='${2h ago}' --end='${1h ago}'
This command would fetch log entries from the "my-log-group" log group within the specified time range.
