Dobrij den'!

A mozete zapustit' netxmsd pod gdb i kogda on upadet, sdelat' backtrace?

Zapusk:

# gdb netxmsd
gdb> run -D 1

Kogda upadet:

gdb> bt

i prislat' rezul'tat komandi bt.

Try to run database check:

nxdbmgr check

Hi!

Most likely the cause is that NetXMS server is stopped. What version you are using and on what platform?

Hi!

I have found and fixed some memory leaks, but no one of them seems to be able to eat memory so fast. However, can you try to install the following version: https://www.netxms.org/download/dev/netxms-1.0.12-rc-19062011.tar.gz? If this will not help, could you please run your server under valgrind for 5-10 minutes and send me the log? Command for running server under valgrind is following:

valgrind --leak-check=full --undef-value-errors=no --log-file=/tmp/netxmsd_valgrind.log /opt/netxms/bin/netxmsd -D 5

To stop server, enter command "down" on server's prompt.

Yes.

Nastroeno vrode vse pravil'no. Pohoze problema imenno v tom, chto snachala oprashivajutsja uzli za vpn gateway'em, a potom on sam. Vlijat' na porjadok oprosa osobo nel'zja. Ja podumaju chto s etim mozno sdelat'.

Dlja otladki scriptov mozno ispol'zovat' funkciju trace - ona vivodit soobschenie v log servera. Format takoj:

trace(debug_level, message)

Esli debug level 0, to budet generitsja INFO message.

Privedennij vishe script s trace'ami mozet vigljadet' tak:


s = FindSituation("VPNBStatus", "B");
if (s != NULL)
{
   trace(0, "Situation instance found, status=" . s->status);
   if (s->status == "down")
      return false; // Don't match rule
}
else
{
   trace(0, "Situation instance not found");
}
return true; // Match rule


Mozno prosto kak foreground process - ostanovit' servis, i zapustit'

nxagentd.exe -D 9 -c <config_file>

Chtobi zapustit' servis v debug rezime, nado v registry pomenjat' command line servisa.

Nu i zelatel'no, chtobi v kachestve loga ispol'zovalsja tekstovij fail, a ne event log.

Hi!

Looks like memory leak in netxmsd. Can you please add to monitoring memory used by netxmsd process and send me how it changes over time?

Hi!

Is it possible that there are low memory condition on NetXMS server? From crash dump it looks like some internal memory allocation fails.

Pohoze chto problema s kodirovkoj servera ili bazi. Kakoj stoit code page dlja non-UNICODE program na servere, gde rabotaet NetXMS server? I kakaja vibrana kodirovka dlja bazi NetXMS?

Ochen' pohoze na nedavno obsuzdavshujusja problemu s parserom logov na Novell NetWare. Vozmozno agent schitaet chto proizoshla rotacija loga, i perechitivaet fail s nachala. A vi mogli bi zapustit' agenta v debug rezime?

A problema s postojannimi soobschenijami "LogParser: file size differs for stat(7) and fstat(SYS:\ETC\LOGs\CONSOLE.LOG), assume file rename" toze tol'ko na 5.1?

Если смотреть на этот файл с Windows-компьютера проводником, то он имеет нулевую длину - может в этом причина ошибки?

Eto vozmozno. AGent sravnivaet dlinnu otkritogo faila s tem, chto soobschaet OS, i esli OS soobschaet men'shuju dlinnu, schitaet chto proizoshla rotacija i nado fail otkrivat' zanogo. Ja podumaje chto zdes' mozno sdelat'.

Hi!

You can try to create custom tool for 1.3.6.1.2.1.4.22.1.2. I'm not sure that all devices supports IP-MIB, so changing default tool to it may not be a good idea. Probably another standard tool based on IP-MIB should be added.

Hi!

Failed SQL queries suggests that there are something wrong with DB connection, but I don't really sure that it's related. Crash dump will be very helpful.
