Is it possible to extend and replace the Remote File Chooser in the WebNMS application client?
Our users want to see the image preview when choosing for example a background image for maps. There is already something similar in the Runtime Administration / Map UI Settings where map icons are shown in the table. So the idea is to have something similar for choosing a map background image. Is that possible?
Thanks & Regards, Lukas
BTW what is the maximal size of attachments and images in this forum? 173 kB image is too large?
In postgre older than 9.0, the VACUUM ANALYZE command needs to be invoked regularly in order to reclaims disk space and make it available for re-use. However, extra space is not returned to the operating system. This can be done only if the VACUUM FULL ANALYZE is used.
Unfortunately VACUUM FULL ANALYZE can not be used when the application is running because postgre needs exclusive write locks for tables in order to do VACUUM FULL ANALYZE.
The NMS gets too slow because of extreme database file growth (from <100MB to 1.6GB in 20 days). Then the application needs to be stopped and VACUUM FULL ANALYZE invoked on database.
Does anyone have some better way to handle this? I will definitely upgrade to postgre 9.1 or 9.2 in about a month, but the upgrade may not necessarily solve this issue.
WebNMS is officially distributed with postgre database since version 5.2.
Is anyone using this solution in production environment? How does postgre scale up compared to MySQL? Do you have some solution for master-master replication between two instances of postgre?
Regarding the last question - we are testing data replication on the filesystem level using drbd, because it seems that there is no other solution for that, but maybe I am wrong, that is why I am asking here.
This is just a convenience list of topics I came accros when looking for a high availability (failover/cluster/redundancy) solution for our WebNMS based application. Feel free to add other links.
DBprice state of master-master replication postgre free not described MySQL $2000/year/server described & works Oracle probably lot more :) * setup described in the manual MSSQL ? not described in manual Sybase ? not described in manual Solid ? not described in manual TimesTen ? not described in manual
I created a trap filter and my intention is that all traps received by NMS should pass through this filter first and then continue to be processed by other trap filters.
So far I has been unable to come up with proper trap filter settings. Based on the documentation the asterisk character (*) should serve as "match-all" criteria. But so far it seems that it does not work as I would expect. It means when I specify the following two criteria at the beginning of the trap.filters file, then both SNMPv1 and SNMPv2 traps will pass through the filters
we are preparing integration tests (test from the user perspective) for our WebNMS based application and I would like to ask other developers and WebNMS support team if you have some useful advices regarding this type of testing.
1. Any advices regarding the testing framework? We are using application client only, so web based testing via e.g. Selenium is not applicable. We have chosen Jubula as a testing framework for swing based GUI and we have couple of test suits, but I am not sure how this will scale up.
Then we have some more concrete problems: 2. How can I install the server automaticaly without asking for license key? I need this as the first step for successful automated deployment.
3. How can I delete all managed objects, events, alarms and map symbols? I need to do this as the first step before each testing scenario in order to get the clear initial state. The important requirement for this is that it must not fail and delete any strange artifacts from the previous failed tests, e.g. map symbols without managed objects, managed objects with broken parent-child and group-member relations etc.
Any suggestions are highly appreciated. Thanks in advance
Did anyone tried to increase amount of memory for the server JVM and check the JVM monitoring details in the WebNMS application client if it shows any values above 100? It seems to me that there is some artificial limit which sets all values exceeding 100 to 100.
