Tongweb crawl performance log script

        You can see from the previous article , In case of performance problems, in addition to opening TongWeb Monitoring function , You also need to manually execute a series of performance analysis commands to troubleshoot problems , because TongWeb The monitoring function of is not enough to analyze the problem . This manual operation is difficult for the project operation and maintenance personnel , Often eager to restore the system , restart TongWeb To solve . Here is a script , Try to crawl all logs once .

# This step is mainly aimed at performance problems , Not all log fetching commands are executed at one time , Even the problem of incomplete parameters .
# Put the script in TongWeb Of bin Under the table of contents , Execute the record once when slow occurs CPU,netstat, Handle ,jstack,kill -3,busy,jmap, If the execution error occurs, skip to continue the execution .
# If you do not have permission to execute under the classified aircraft , Through    . ./slowlog.sh The way to carry out , Notice that there are spaces at two points .
# After the execution TongWeb Of logs The contents are packed and kept at the bottom .
# if JDK Incorrect environment variables , Remember to set PATH Variable . Want to have jstack、jmap、jstat Commands can't just be installed jre.
