Main Page Open the CNAF instance at
https://cert-wms-01:8443/wmsmon/main/main.php
Notice that you need a certificate in your browser in order to access it.
Once in the main page you will see a table with 1 row for each WMSLB instance monitored with a sintethic overview of instance status across columns
Notice that a filter to find VO dedicated WMSLB instances is provided
The following columns are reported:
WMS: specific WMS instance hostname. Clicking on it you will access the relative detailed data page, described below
DATE: date/time of last measurement

The following columns are reported:

WMS DATE RUNNING
JOBS
IDLE JOBS WM QUEUE JC QUEUE VO VIEWS LB EVENTS QUEUE CPU LOAD SANDBOX PARTITION GENERAL STATUS DAEMONS STATUS
Specific WMS instance hostname. Date-time of last measurement Number of jobs in the state "Running" in the condor Number of jobs in 'Idle' state in condor Number of entries in input.fl Number of entries in queue.fl This is calculated as:
-number of VO Views used in last Match making from workload Manager as reported in 'workload_manager.log'
or
-number of entries in ismdump.fl if last MM is older than 1 hour.
None is returned in case none of the two measures above is successful.
Number of dg20logd_* files in directory /var/tmp. (Events not yet stored in the LB server DB) Average load of the machine during the past 15 minutes Occupancy (in %) of directory /var/glite/SandboxDir This is a FLAG:
-Green-Yellow-Red depending on whether all main variables status measured is OK, or at least one variable is in Warning or Error status respectively
This is a FLAG:
-Green-Red depending on whether all WMSLB daemons returned a normal status, or at least one returns an Error status


Clicking on WMS hostname or one of the STATUS flags you will access the relative detailed data page, described below.

Short Description of the tool

WMSMonitor monitors two kinds of variables:
>
>
Here, more info are made available on the specific WMS instance.
Two kinds of data are collected:
 - WMSLB service and HW status variables (such as daemons status, condor jobs status statistics, File descriptors opened by main processes..) for which the value at the time of measurement is shown
- Mean job flow rates between wms components (WMproxy, Workload Manager, Job Controller, Condor) across a given time interval reported as well (across past 15 min is the default)
Added:

Notice that: - A short automatic help on mouse pointer positioning over main buttons and variables
- Passing the mouse pointer on charts a window will pop up with the correspondent variable values and date of measurement.
- A link to lemon monitoring of the specific instance (both WMS and LB if on separate machines) is available
 *UNDERSTANDING CHARTS*
For most relevant variables, charts with recent history (whose time interval can be selected) are made available
*Components Report History*
Line: 64 to 58
 Jobs->JC: for each point reports the total number of jobs enqueued to Job Controller from Workload Manager for correspondent day.
Jobs->Condor: for each point reports the total number of jobs enqueued to Condor from Job Controller for correspondent day.
