These are generic UNIX instructions ie. if you don't have MySQL, Apache or PHP installed.
What you need:<>
Basic Install Process
This is assuming that you are on a UNIX/LINUX machine *
Get an Apache version from www.apache.org. These instructions assume Apache 1.3.x. When compiling apache, you need to compile it so it can use mod_so. This allows other modules to be loaded (php) when you start the httpd server.
./configure –enable-module=so && make
before you do a make install, you
should be able to find the httpd in the ./src directory.
you should get a list that shows you all the modules...the one we are looking for the most is, mod_so.c. If that is there, we are good to go for now.
When compiling php4, you need to have in your $PATH where apxs is installed. It should be under the $PREFIX/apache/bin/apxs. If you don't have this, go back and reinstall apache.
./configure –with-mysql=/usr/local/mysql –with-apxs --enable-track-vars --with-gd --enable-gd-imgstrttf --with-ttf' –with-ldap –enable-gd -native-ttf --with-pgsql && make && make install
I downloaded the binary for it and simply untar'd it in a directory. The binary is available for all platforms so you don't need to compile it.
One thing I did notice about the binary was when I tried to run ./bin/safe_mysqld –user=mysql it gave me an error about no libexec directory or var directory. After further review, the ./bin/safe_mysqld, which is a shell script, had some incorrect data. Simply edit safe_mysqld, and look for libexec and substitue it for bin, then look for var and substitue it for data.
AS ROOT: (assuming you are installing in /usr/local)
This is documentation quoted directly
from the INSTALL-BINARY by mysql.
You can download the binaries at the
address below. They are available for almost any platform.
Working with phplicensewatcher
Ok, now you have a working apache, php4, mysqld, lmutil and you're ready to get what you've been wanting for over about an hour now.
Making sure that safe_mysqld is running:
ps -ef | grep mysqld |grep -v grep
If you get something, you should be alright.
Become the mysql user (or root) then
This creates the database called licenses.
Please ignore "Unknown table" errors (if tables
with same name are found they are dropped). This populates the
database with tables and such.
I recommend creating a MySQL user with
only INSERT or SELECT privileges to the tables. To create a user called
lic_user with password secretpass type
Then type or paste following
Ok, now we are
ready to set the password on the mysql database and in this case,
you actually want to use the apostrophe with new-password being your
new password and not the word new-password.
There is a sample-config.php in the
phplicensewatcher directory. Copy it to config.php ie .
cp sample-config.php config.php
then edit it in your favorite editor.
You want to keep
an eye on the following:
$lm_home = "/usr/local/bin"; // location of lmutil and lmstat
$servers = "27000@hostname";
$description = "Synopsys License";
If you have more then one host, or more then one port active, just keep adding a $servers line and a $description line.
$servers = "5280@hostname";
$description = "Cadence Licenses"; // and so on and so on
By default you will be warned 10 days ahead of time whether licenses are expiring. If you want to prolong that or shorten that adjust the $lead_time variable ie.
$lead_time = 10;
You now have to configure your database settings. This assumes you
are using MySQL. You could use other databases but you would need to
$db_hostname = "localhost"; // localhost should work if it is in /etc/hosts
$db_username = "mysql"; // name of the user who starts the safe_mysqld
$db_password = "mysecretpassword"; // whatever you changed your password to
$db_database = "licenses"; // name of the database.
# Leave $dsn as it is if you are using MySQL.
$dsn = "mysql://$db_username:$db_password@$db_hostname/$db_database";
# Uncomment following if you are using PostGresSQL and comment out one with MySQL
# $dsn = "pgsql://$db_username:$db_password@$db_hostname/$db_database";
PHPLicensewatcher will record
utilization for all the licenses listed on the servers you are
watching. However in most cases you will want to keep an eye on couple.
That is why you need to specify couple features you want graphed on the
utilization page. To do that you have to add $license_feature and
$feature_description pairs. License feature is the actual name of the
feature as used on the license server ie. Al_viewer while feature
description is a more detailed description of the feature
$license_feature = "Al_viewer";
$feature_description = "Allegro Viewer";
$log_file = "/mnt/flexlm/27000-at-licenserv.log";
If everything worked without errors,
then you should be able to point your browser to
This is probably the most important part of managing licenses :-). Being notified when licenses are due to expire. E-mails come as HTML mail since I wanted to use tables and colors.
The way I use it is to run license_alert.php report every night at 2 a.m. This report will query all specified license servers and figure out which licenses are due to expire. There are two ways to run license_alert.php script. You can use PHP interpreter directly if you have it installed in on your machine ie. RedHat distributes php interpreter as php-*.rpm packages. You can then have one of the following entries in your crontab
0 2 * * * php /var/www/html/phplicensewatcher/license_alert.php >> /dev/null
The other way to invoke it is to use wget which is a web retrieval tool. You can also use curl if you prefer that
0 2 * * * wget -O - http://your.apachehost.com/phplicensewatcher/license_alert.php >> /dev/null
License_cache.php stores the total number of available licenses on particular day. This script is necessary because you may have temporary keys that may expire on a particular day and you want to capture that. It should be run once a day preferably soon after the midnight after which license server should invalidate all the expired keys.
My crontab looks like this
0,15,30,45 * * * * wget -O - http://your.apachehost.com/phplicensewatcher/license_util.php >> /dev/null
15 0 * * * wget -O - http://your.apachehost.com/phplicensewatcher/license_cache.php >> /dev/null
An important metric in evaluating your licenses is license denials
how many people were denied access to a certain feature because we were
of licenses. To do that we have to analyze FlexLM logs. FlexLM logs are
during FlexLM start up. For example we start our FlexLM servers with
su nobody -c '/tools/lmgrd -l /usr/tmp/27000-at-licenserv.log -c /tools/license/license.dat'
This will create /usr/tmp/27000-at-licenserv.log which will contain information such as when the license has been checked out, when it was checked in plus any time a license has been denied ie.
16:01:20 (daemond) DENIED: "viewer" jack@server (Licensed number of users already reached (-4,342))
We want to capture this information since a high number of denials
indicate that we should consider getting additional licenses since a
of people are being denied access.
Same log file contains check out and check in information that we
also store in the database so we can retrieve it later.
FlexLM logs can be very large so it may take a long time to analyze them. I run the analysis scripts around 2 a.m. every morning. To run them put something like this in your crontab
0 2 * * * wget -O - http://your.apachehost.com/phplicensewatcher/parselog.php >> /dev/null
1. I go to license utilization page and
I can't see any graphs ie. not even the grid shows up
There couple reasons
2. DB Error: connect failed
Either lic_user doesn't have appropriate
privileges or you are pointing to the wrong database
