< Erlang questions mailing list ~ No more EVA?

Hi All,

I wonder why did Eva get withdrawn from the latest Erlang/OTP release? Is it because any
commercial/license issue, since it's outdates or replaced by any other package?

Thanks!
Eranga

Hi,

The Eva application was withdrawn from the R10B release because:
- we knew that no commercial user (i.e paying) was using it.
- we did not know any open source user using it (but we have heard of some
after the decision)
- Eva needs to be updated due to dependencies to snmp which has got small changes
in the API's and we did not think it was worth the effort since nobody is using it.
- There are other event and alarm solutions that could be included in OTP some day if
the interest is big enough.
- If someone really need Eva it should be easy to take Eva from R9B ,
do some minor corrections
and run it together with the rest of R10B.

Hi Kenneth,

Thanks for your advice.

I would like to see a good event and alarm solution in OTP, since I think
it's a most important part in a system. It'll be really helpful, if you can
advice me what're the other event and alarm solutions you hinted below, so I
can see to integrate them and can give back to the community, if it'll be
any use.

Cheers,
Eranga

Hi,

The other event and alarm solution is part of a product we have
(written in Erlang) and is not that easy to extract as a separate generic
application. I meant that we (Erlang/OTP developers at Ericsson) could extract that
solution and include it in OTP when and if interest is big enough.
We do not have that in our current plans for what to do during 2005.

I looked at EVA a few years ago when writing the event and alarm code
for an embedded system. That system didn't need SNMP and didn't have
mnesia, so that left me looking at 11000 lines of code which don't do
a whole lot more than remember which alarms are on and and tell other
processes about it. Seemed about as much help as having someone else
handle the fork while I'm eating ravioli, and a lot less fun.

It seems that others have arrived at the same conclusion: in 99.9% of
applications, EVA is more trouble than it's worth. I suspect that
holds for all canned alarm solutions.

But just because EVA was removed from the distribution doesn't mean
you can't use it. It's still available for download.

Hi!

No, you're not the only one. See for example http://www.3gpp.org/.

The application cosTime supports similar functionality as Eva. You should
also look into cosNotification (alt. cosEvent), which is used by 3GPP to
handle Events/Alarms.

Hi Matthias,

With the little reading I did on EVA, it seems to me more than an event
handler. It contains SNMP adaptation support and log management. First I
thought it's pretty helpful though withdrawal gave me second thoughts.

A year ago, when I was trying to convince my
then-company to use Erlang, an event-alarm app was part
of the goodies I listed. It's consistent with the sort
of systems Erlang is very suitable for.

I'm not convinced I would have ended up actually using
it, as against rolling our own.

And these days, I have no use for it: I'm more
interested in the pure Erlang language than in OTP and
the apps.

If there are plans to withdraw EVA from distribution, does it mean that OS_MON will be excluded as well? There is a dependency of OS_MON on EVA in the OTP-OS-MON-MIB.mib:

IMPORTS
currentAlarmObject, currentAlarmSeverity, currentAlarmTime
FROM OTP-EVA-MIB

What are the OTP team's future plans for dealing with this? I suppose it would be best to eliminate this dependency by either creating another MIB with these alarm objects defined, or incorporate them in the OS_MON or SASL.

Regards,

Serge
