WEBLOGVIS(1) General Commands Manual WEBLOGVIS(1)
weblogvis - visualize activity and performance from Web server
logs
weblogvis [-bCfiVz] [-A align] [-a archive] [-h host] [-I time]
[-m max] [-n pmnsfile] [-O time] [-p port] [-S time] [-t interval]
[-T time] [-x version] [-Z timezone] [server ...]
weblogvis displays Web server activity as extracted from the Web
server access logs by the Performance Co-Pilot (PCP) agent
pmdaweblog(1). The display is modulated by the values of the
performance metrics retrieved from the target host which is
running pmcd(1) and the pmdaweblog(1) Performance Metrics Domain
Agent (PMDA(3)), or from the PCP archive log identified by
archive. The display is updated every interval seconds (default 2
seconds).
The default display mode shows the request rate classified by
request response size, for all Web server logs being monitored by
pmdaweblog(1). The top of the display includes the idle time and
the total request rate of each Web server. The list of servers
can be restricted by specifying server names. The possible
servers are listed in the pmdaweblog(1) configuration file.
weblogvis uses pmview(1), and so the user interface follows that
described for pmview(1), which in turn displays the scene within
an Inventor examiner viewer.
weblogvis passes most command line options to pmview(1).
Therefore, the command line options -A, -a, -C, -h, -n, -O, -p,
-S, -t, -T, -x, -Z and -z, and the user interface are described in
the pmview(1) man page.
The weblogvis specific options are:
-b Change the display mode to report bytes per second, rather
than requests per second.
-f Change the classification of activity to use HTTP functions
(Get, Post, Head and Other), rather than the default
classification by request result size. With this
classification, the error rates from the logs for each Web
server are also displayed.
-i Label each column with the name of the Web server.
-I time
Change the dafult expected idle time for the Web servers
from 3600 seconds (1 hour) to time.
-m max Change the default normalization maximum to max
bytes/second or requests/second, depending on the display
mode. The defaults are 500000 bytes per second or 100
requests per second.
-V Verbose mode - output the generated pmview(1) configuration
file.
$PCP_VAR_DIR/config/pmlogger/config.web
pmlogger(1) configuration file that can be used to create a
PCP archive suitable for display with weblogvis
$PCP_VAR_DIR/config/pmchart/Web.Alarms
pmchart(1) configuration file for monitoring Web server
alarm conditions
$PCP_VAR_DIR/config/pmchart/Web.Requests
pmchart(1) configuration file for monitoring Web server
requests
$PCP_VAR_DIR/config/pmchart/Web.Volume
pmchart(1) configuration file for monitoring the volume of
Web server transactions
$PCP_PMDAS_DIR/weblog
installation directory of pmdaweblog(1)
Environment variables with the prefix PCP_ are used to
parameterize the file and directory names used by PCP. On each
installation, the file /etc/pcp.conf contains the local values for
these variables. The $PCP_CONF variable may be used to specify an
alternative configuration file, as described in pcp.conf(4).
pmcd(1), pmchart(1), pmdaweblog(1), pmlogger(1), pmview(1),
webpingvis(1), webvis(1), pcp.conf(4) and pcp.env(4).
