Top Forums Shell Programming and Scripting Extracting Latency, Loss and Jitter from PING responses. Post 302265268 by tony.kandaya on Saturday 6th of December 2008 07:51:56 AM

Thanks for your input... I modified extract-sla script as follows

awk '
/^PING / {h=$2}
/packet loss/ {pl=$6}
/min\/avg\/max/ {
split($4,a,"/")
printf("a=%s b=%s c=%s d=%s\n", h, a[2], a[4], pl )
getline < "mysql-update-infile"
print
}
' ping-results-1.txt > mysql-update-tables

********

The above script produces a mysql-update-tables file in the format below, line by line (might not be the best way to do it, but it worked for me)

a=Host11 b=52.960 c=10.466 d=0%
/usr/bin/mysql -h 10.255.1.11 -u ping --password='ping' -D host_SLA -e "UPDATE device_list SET latency='$b', jitter='$c', loss='$d' WHERE host='$a'"

I then put all the pieces together using one script and cron the job.

** btw I did not have to delete the '%' in variable 'd'

Thanks for your help

MYSQL_TZINFO_TO_S(1)					       MySQL Database System					      MYSQL_TZINFO_TO_S(1)

NAME
mysql_tzinfo_to_sql - load the time zone tables SYNOPSIS
mysql_tzinfo_to_sql arguments DESCRIPTION
The mysql_tzinfo_to_sql program loads the time zone tables in the mysql database. It is used on systems that have a zoneinfo database (the set of files describing time zones). Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X. One likely location for these files is the /usr/share/zoneinfo directory (/usr/share/lib/zoneinfo on Solaris). If your system does not have a zoneinfo database, you can use the downloadable package described in Section 10.6, "MySQL Server Time Zone Support". mysql_tzinfo_to_sql can be invoked several ways: shell> mysql_tzinfo_to_sql tz_dir shell> mysql_tzinfo_to_sql tz_file tz_name shell> mysql_tzinfo_to_sql --leap tz_file For the first invocation syntax, pass the zoneinfo directory path name to mysql_tzinfo_to_sql and send the output into the mysql program. For example: shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql mysql_tzinfo_to_sql reads your system's time zone files and generates SQL statements from them. mysql processes those statements to load the time zone tables. The second syntax causes mysql_tzinfo_to_sql to load a single time zone file tz_file that corresponds to a time zone name tz_name: shell> mysql_tzinfo_to_sql tz_file tz_name | mysql -u root mysql If your time zone needs to account for leap seconds, invoke mysql_tzinfo_to_sql using the third syntax, which initializes the leap second information. tz_file is the name of your time zone file: shell> mysql_tzinfo_to_sql --leap tz_file | mysql -u root mysql After running mysql_tzinfo_to_sql, it is best to restart the server so that it does not continue to use any previously cached time zone data.
