Automated Diagnostic Data Collection

• -i:  Specifies the logging interval in seconds and determines how frequently the script checks and records system metrics. If you omit this flag, the script automatically applies a default interval of 180 seconds.  
  Default Value: 180 seconds
   

• -s: Specifies the script execution duration in seconds. The script terminates automatically once it reaches the configured runtime. If you omit this flag, the script runs continuously until you manually stop it. 
  Default Value: Runs forever

• -c: Specifies the system metric that the script monitors. Provide an integer value from 1 through 7 to select your target metric.
  
  For details about value range, see Condition (-c) Reference.
  Default value: N/A
   
• -l: Defines the threshold for the monitored metric (specified in -c option).
  
  For example, -c 6 -l 90 triggers the configured action when CPU usage exceeds 90%.
  Default value: N/A 
   
• -p: Specifies the target application or process for the script to monitor against your configured performance thresholds (-c and -l). Provide an integer value from 0 through 6 to select the process. When the monitored process exceeds your defined threshold, the script executes the configured trigger action.
  Default Value: 0 (All applications)
  
  For details about values, see Process (-p) Reference.
  
  For example: -p 1 -c 6 -l 90, triggers the configured action if the mwg-core process hits 90% CPU usage. 

Chains multiple -c and -l pairs to create complex trigger conditions.

Example for  AND condition:

mwgResInfo.sh -p 1 -c 5 -l 8.0 -AND -c 4 -l 1000 -AND -c 6 -l 75 \ -e "gcore -o /opt/mwg/core_dump \$(pgrep -n mwg-core)" -ot -noLog 

ALL specified conditions must be true simultaneously to trigger the action. 

Example for OR condition:

mwgResInfo.sh -p 1 -c 2 -l 5000000 -OR -c 3 -l 5000 \ -e "/etc/init.d/mwg restart" -noLog 

If any of the above specified condition is true, an action will be triggered.

• -e: Specifies the command or action that the script runs when a monitored metric exceeds its threshold. When system metrics meet the conditions defined by the -c and -l flags, the script automatically executes this specified command.
  Default Value: N/A
  
  For example:
  -e "/etc/init.d/mwg  restart" automatically restarts the service when the trigger condition is reached. Multiple commands can be specified using this option.
  
  For example:
  -e "echo "Capture for reaching threshold" | /opt/Skyhigh/ldt/getlogs/getlogs.sh /opt/mwg/debug ; gcore -o /opt/mwg/log/debug/mwg_core_dump $(pgrep -n mwg-core); /etc/init.d/mwg restart"
  
   

• -ot: Executes the command specified by the -e flag only once when system metrics first meet your threshold condition. This restriction prevents the script from repeatedly triggering the action while the monitored metric remains above your configured threshold.
  Default Value: N/A
   

• -n: Terminates script execution after system metrics meet your threshold condition for the first time. Upon reaching the threshold, the script executes the command specified by the -e flag (if defined) and exits immediately. If you omit this flag, the script continues monitoring in the background after a trigger event occurs.
  Default Value: N/A 

• -noLog: Disables the creation of metric log files. By default, the script continuously records monitored statistics (such as CPU and memory utilization) to local disk log files (for example,mwgResInfo*.log). 
  
  Use this option to operate the script as a lightweight background watchdog that silently monitors the system and executes your configured -e action the moment system metrics breach your defined thresholds.
  Default Value: N/A
   

• -gl: Enables automatic, periodic collection of system logs by executing the getlogs utility at regular intervals. The script saves the resulting compressed ZIP archive to the local debug directory (/opt/mwg/bin/../log/debug/getlogs_<timestamp>.zip). If the host system lacks the getlogs utility, the script automatically attempts to install it. This function operates completely independently of any monitoring thresholds (-c or -l) or trigger conditions. 
  Default Value: N/A
   

• -gi: Specifies the collection interval in seconds for the getlogs utility enabled via the -gl flag. If you deploy the -gl flag but do not specify the -gi parameter, the script automatically applies a default execution interval of 86,400 seconds (24 hours). 
  
  Example:
  To instruct the script to collect logs every hour, append -gl -gi 3600 to your command string. Default Value: 86400 seconds (24 hours).
