Symptoms

What is Calypso? How does it work? How does Calypso speed up SR resolution?

How to collect and analyze log files from Service Assurance Suite (Watch4net) and ViPR SRM.

Cause

Calypso is designed to simplify log collection and speed up the analysis of your Service Assurance Suite (Watch4net) and Vipr SRM issues.

Resolution

Calypso designed to simplify log collection and speed up the analysis of your Watch4net, Vipr SRM and SA Suite issues.

Calypso uses SSH to connect to the specified ViPR SRM or SA Suite frontend and obtain information on the other hosts registered with the Centralized Management.

It then uses SSH to run diagnostic2.sh and detect.sh on each of the registered hosts.

DOWNLOAD CALYPSO:
============

Calypso is available to download from the "Tools" section of the Service Assurance Suite and ViPR SRM product pages:

https://support.emc.com/products/31946_Service-Assurance-Suite/Tools/

https://support.emc.com/downloads/34247_ViPR-SRM

INSTALL CALYPSO:
============

Unzip the calypso_<version>.zip into a folder on a Windows host with access to the ViPR SRM or EMC M&R Frontend host.

USAGE:
============

Run either of the commands: calypso.bat or calypso.bat 0:

When invoked with a parameter of 0, calypso will only run the detect.sh script on all the hosts registered with the Centralized Management. No diagnostic.sh output will be collected.

Example:

C:\Calypso\Calypso_1.7\Calypso_1.7> calypso.bat
--------------------------------------------------------
Calypso 2.3 - SRM/SA/W4N Diagnostic Log Collection
--------------------------------------------------------
Please note that for Calypso to work, the Frontend host must be able
to resolve the other hosts by using DNS or the hosts file.
Calypso uses SSH to log into hosts, therefore no host collection will be
obtained from Windows hosts. For Windows hosts, the APG/bin/diagnostic.cmd output
has to be obtained manually.

Enter the Frontend (FE) hostname or IP: 1.1.1.1

Enter the FE host username, or press ENTER for root: <ENTER>

Enter the FE host password, or press ENTER for default password
Password: *********

Enter the installation directory, or press ENTER for /opt/APG:

Press ENTER to collect diagnostics for all hosts registered with Centralized Management on the Frontend host OR enter space-separated FQDNs of selected hosts for which diagnostics will be collected
Available hosts:
vm_APG_host
: <ENTER>

Press ENTER to get diagnostic2.sh to collect logs for only the last 3 days which should be sufficient in most cases OR enter the number of days the logs will be collected for
: <ENTER>

If there are Windows hosts in the installation, they are listed below.
Please note that NO DIAGNOSTIC DATA will be collected for these hosts.

... invoking diagnostic2.sh in parallel on SRM hosts
... waiting for background jobs to finish
... all background jobs now completed
... invoke background download of DiagnosticFiles for Host

... running detect on Host
... waiting for background jobs to finish

... all background jobs now complete
adding: out/detect_Host.htm (172 bytes security) (stored 0%)
adding: out/info.txt (172 bytes security) (deflated 33%)
adding: out/servers.xml (172 bytes security) (deflated 26%)

Enter the Service Request number or press ENTER to skip uploading the files to ftp.emc.com: <ENTER>

Files for EMC support are stored in .\out. Press ENTER to exit ...<ENTER>

CALYPSO OUTPUT:
===============
Calypso will produce the following files in its out directory:

detect.zip

DiagnosticFiles_<hostname>.tar.gz

The detect.zip contains the following files:

out\info.txt
---------------------
This file contains the calypso version and the version of Tomcat on the Frontend host, which should correspond to the installation version.
The NSLOOKUP section contains the IP address for each host.
The HOST PERSONALITY section allows to determine if the host is a Frontend, Backend or Collector.

detect_<hostname>.txt
---------------------
The layout of this files is as follows:

COLLECTORS

Here you will find all the installed solution pack instances and their configurations on the host.

BACKENDS

Here you will find all the installed backend instances and their configurations on the host

FRONTEND

Here you will find all the installed frontend instance and its configuration on the host

SERVICES

The list of ViPR SRM and EMC M&R services and their status

TASKS

The list of scheduled tasks and their status

LOG ANALYSIS

Here you will find a list of 20 ERROR and WARNING messages from the current log files for the Frontend, Collectors and Backends.

A line following the ERROR or WARNING is included as this line usually contains useful relevant information

metrics_<hostname>.txt
---------------------
This file contains the number of "active" (vstatus == 'active') objects of various types in each MySQL database on the specified host.
For example, the number of VMAX arrays, VMAX devices and VMAX pools are shown. This is for future use in the ViPR SRM Workbench.
The second number is the number of objects irrespective of vstatus setting.

Related Information

When opening a Service Request with Customer Support, please include the output from this tool in the SR (eg: "Calypso 0") as it will greatly speed up resolution and in many cases points to the cause faster than a webex can.
