Sunil,

I have DECevent V3.3 installed and running on OpenVMS VAX V6.2 - why shouldn't it work on V7.1 ? If you have a problem installing or running DECevent V3.4 on OpenVMS VAX V7.1, please provide a problem description.

As already said in the previous thread, DECevent is a service tool to translate and analyze OpenVMS ERRLOG.SYS files:

What kind of problem are you trying to solve or what kind of functionality are you looking for ?

Volker.

Hi,

I understood from the docs that DECevent can give alarms related to upcoming hardware failure such as disk failure,cpu failure, meme failure etc....

Same options are covered, if am not wrong, in Polycenter watchdog.

Iam looking for product whcih is similer to this..
should I go for DECevent or Watchdog...

HOw usefull is tools, tell from your experince...

Sunil,

in DECevent, this functionality is called 'error analysis and notification' and requires a DECEVENT PAK (Product Authorization Key), which you can only obtain from HP or an authorized service provider, if you have hardware service for your server.

DECevent supports only some systems and components for analysis and notification (see documentation) and 'the idea' is, that once spurious errors show up on a device supported for analysis, then DECevent will automatically start to analyse all the device entries in ERRLOG.SYS and - if this failure mode is recognized in the DECevent knowledge rule set - send mail to the system manager to schedule a repair action.

The goal is to prevent a fatal error and schedule maintenance, before the component finally fails. It worked fine in the days of failing HDAs (e.g. RA82 disks).

Polycenter System Watchdog changed it's name to Unicenter TNG Event Manager a long time ago. This is a licensed product sold by CA and seems to now be called: Unicenter System Watchdog for OpenVMS. Besider many other things, it seems to also monitor hardware errors (but it will certainly not deliver the analysis capability like DECevent).

Sunil, as I recall DECevent didn't install on VAX.

Lawrence,

DECevent does instal on OpenVMS VAX, there is a separate kit DIAV034 for installation on OpenVMS VAX.

Is DecEvent nessesary to use the command:
"analyze/error" now adays?

On my server with OpenVMS 7.3-1 I get:

$ analyze/error
Error Log Report Generator Version V7.2

%ERF-F-CEHFND, New header format found. Install DECevent and run conversion utility
$

DECevent uses the "$ DIAGnose" verb. Most commands are substantially the same as
"$ analyse/error". e.g.
$ anal/err/brief/since=-3-::. (3 days ago)
$ diag /brief/since=-3-::.

There are some variations, but it is all documented in the help files, however, the choice of tool depends both on what machine you have and which version of VMS.
VAX: All versions, $ anal/err.
Alpha
EV4, V7.1-x and older. ERF ($ana/err)
EV5,GS80/GS140 and V7.2 or later: DECevent
EV6 except GS80/GS140: WEBES.
This isn't a definitive list, as I have summarised it and being still on V7.3-1 have yet to see the replacement for ERF on V7.3-2 and later. Also I haven't got an Itanium system yet to play with... (any donations ? :-)

Rolf,

the ERRLOG.SYS file format has changed on OpenVMS Alpha with V7.1-2 (new Common Event Header format).

Only DECevent (or Compaq Analyze/SEA) can read this format.

Since OpenVMS V7.3-2, there is the new ANAL/ERR/ELV utility (Errog Log Viewer), which can also understand the new format.

Volker.

Does the anal/err/elv understand the ES40 and DS10/20, etc specific errors or do we still need to install Webes?

Re: DECEvent

Volker Halle — Fri, 04 Mar 2005 02:07:47 GMT

Cass,

ANAL/ERR/ELV provides a very basic bit-to-text translation for ERRLOG.SYS - now there is at least a tool in the base OS, which can read ERRLOG.SYS.

It is NOT a replacement for WEBES (SEA), which provides more detailled bit-to-text translation and also analysis and notification (on the supported platforms).

Volker.
