im using mysql version 5.5.4

Are there any known issues with 2.0.1 and sqlite  ?  I constantly get "Your database  has format version -1 but server is compiled for version 392"   I have deleted the db and re initialzed it and also upgraded it and after I reboot  I get the same error  and have to do it all over

Is it possible to setup a threshold based on multiple DCI values ?  So if I have four DCI's and I want to sum the values provided by all four and only trigger and alarm if the sum of those four DCI values is >= 50   


Thanks

Is it possible to cause a node to show as down from an external nxpush event ?   My reasoning for this is that we have lots of critical nodes that i would like to monitor less than the 60 sec interval for instance ping every 10 seconds or liess and I dont want to do this on the server because im sure decreasing the status interval to 10 seconds would cause the server to burst into flames  ... but i would like to create a script that could do that and then send the results back to netxms say 0=ok  and 1=down     and have it create and alarm and just like it would if netxms was doing the ICMP requests..  I have experimented with nxpush and it seems i can only provide 0 - 4   from Warning to Critical but never a sys_node_down event

Thanks

Is it possible to add a feature where each device type is at its own layer on the world map and topology map so that when viewing you can select which devices you want to view.. Its gets pretty crowded when you have lots of devices which have lots of connected devices and you only want to see one type of device.. It would also be nice if you could right click on a node and select to either show in map or show in topology and it would take you to and pinpoint that device in either of those layouts

I have read and watch serveral videos and Im trying to wrap my head around netxms polling methods and how it determines if a node is up or down.  In 1.27 I noticed a status DCI which to my understanding was a basic ICMP check now in 2.0 I dont see that created so what is the process ?  does it depend on if the capabilites of the device ?   If it finds a device that doesnt have an agent or doesnt have snmp  does it continually try these methods when running checks in the future ?  and if a device does have snmp what method does it use to determin status both icmp and snmp or just snmp  .......sorry for long post   

Is netxms capable of handling 2000+ monitord nodes ?   I have a dual 4 core server with 20gigs of ram and netxms seems to be choking  I constantly get down events of devices that are not down .. it seems its not handling this very well    What would be the suggested variables for such a setup ? Im using percona server for the db which is supposed to be a more optimized mysql replacment....



Thanks

Did some of the configuration variables change ?

NumberOfStatusPollers    If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/10 of host count.
NumberOfConfigurationPollers    If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/20 of host count.


I no longer see these in the configuration and if things did change could you make a list of what changed or whats new ?

Need help with this i am trying to cross compile just the agent for a device that uses an older kernel 2.6.26.8  with gcc version 4.2.1  and always have issues with  __sync_add_fetch_4  error and I know it is becuase of the older gcc version  is there any way around this ?  This device does not have snmp support which is why I would like to have an agent running on it ...

I have successfully compiled different programs for this devices but having issues on netxms agent


Thanks

maybe add support for mqtt in order to recieve sensor and other data easily with out having to compile nxevent etc for embedded devices..

Maybe a bug in mib import for 2.0  tried importing mib that  was successfull in 1.2.17 but never shows up in mib explorer on 2.0  it does compile without error but just never shows up in the tree

Hey guys,

I was looking into getting support for these devices added  but thought I would give a go at compiling the agent and was successfully able to install the agent/client  on the ERL I havent tried the ER PRO yet but I know it almost the same. My idea was throw one of these inexpensive boxes in each segment or remote location doing icmp checks or snmp checks and ship that info back to the server to allow the server to focus on more demanding tasks ...If any one has any thoughts on this as to why this may not be a good idea please let me know...



Thanks,

Quick question is the GPS tracking feature only supported for mobile devices ? Im not seeing any reference to GPS any where any any of the Manuals ... is it possible for  regular laptop with gps attached to update coordinates back to the server via the agent ?  If so I dont see any configuration params in the conf file ..


Thanks

Is it possible to do IP and Mac address lookups vi nxshell or other command line tools.  I would like to be able to use a script to query where a particular mac address is connected with out having to log in using the client .  I didnt see any options listed in the nxadm  or in the nxshell api  but I could have over looked something.


Thanks

Has any one gotten V3 to work correctly ?   Ive tried both 1.2.17 and 2.0RC  and it seems to have issues in both versions .. Im querying a switch for sys.name and I can pull that same information using SNMPB client  no problems but every time i try netxms i have problems  is this a known problem

is it possible to change the icon and icon size of the world map nodes in 1.2.17 ?  It would be nice to be able to set these parameters since it can be unreadable if you have nodes that are in close proximity ... Also being able to right click and connect via ssh or web browser would be big help...  I looked in the docs and forum and couldnt find any info on this ...


Thanks

Question ... is there any way to get external events into netxms ? i already use graylog2 for syslog so iwould rather not set up another sysylog server ...for instance i use arpalert to monitor any unauthorized mac address or ip on the network and can execute a script based on those alerts so i would like to genrate an alert and send it to netxms for further processing ... is this possible

Could you add a oui lookup table or allow the user to download the IEE oui database and upload it to the server this way when macaddresses are discovered or when your looking for a particular mac address it will also show you the Vendor associated with the MAC ... As well as being able to generate a report based on vendor...  example if i want to find out how many Axis encoders I have in the system i could look that up based on the current snmp info that was gathered previously ......



Thanks,

P.S   This is by far the best NMS I have found compared to the previous if have tried    PandorasFMS, Zabbix , libreNMS ,and Nagios  Thanks for your hard work

Why does the 2.0-RC2  Server Continue to send the public community string ?  I have configured  only one community string in the snmp credentials tab   but  the wire shark capture show the server sending out several requests that use public and then several requests with my custom community string which is causing a lot of problems since our switches willl no longer respond to snmp queries after so many failed attempts. I looked through the configs and folders and cannot find any where this is configured unless it is hardcoded into the software
