Hi!

It is backslash, so

println "\"";

for example will print single quotation mark character. Maybe there are other error in your script?

I thought I read the manual, but I only see %1-%99 events parameter numbers 1..99, but how can I determin what which number does? Is this the ID from Event Editor?

Numbered parameters are event-dependent, you can open Control Panel -> Events, open event of interest, and look at the description - for all predefined events there are list of parameters.

Добрый день!

Это баг в nxdbmgr. Он исправлен в 1.0.0-rc1 - попробуйте использовать nxdbmgr из новой версии.

Problem with MySQL is already known, and I'll fix it in rc2. In the meantime, you could try to prefix ./configure with LDFLAGS=-lmysqlclient, like this:

LDFLAGS=-lmysqlclient ./configure --with-server --with-mysql

Nobody reports PostgreSQL problem so far. Could you please post config.log from failed PostgreSQL configuration?

Hi!

StatusPollingInterval is a global parameter, and if you reduce it, all nodes will be polled more often. Depending on number of nodes, this may cause performance problems. One possible problem is network traffic increase, other is increased CPU and database usage. But severity of both these problems depends on number of nodes.

It's strange that you don't get data collection errors on Agent.Uptime - looks like a bug, because "data collection error" threshold should fire in that case. I'll check this.

Unfortunately all possible workarounds involves local agent. You can enable watchdog for local agent to restart it automatically in case of agent's crash, but it's workaround for workaround The only good solution I see is to allow status polling interval configuration for each node - it's on my todo list for some time, but I cannot promise exact version where this feature will be implemented.

If you need to compare two values in NXSL, you should use == operator. Operator = is an assignment. So, if your script really uses = instead of ==, it's one mistake. Also, don't forget that any event passes all rules, except if matching rule contains "stop processing" option. You have to add it to your rule. Also, interface name always passed as parameter number 2 with SYS_IF_DOWN and SYS_IF_UP events, so you can compare just it's value to {5757FA85-B187-42A4-981C-7443B4ECFC90} instead of comparing full message text. So, I suggest the following rule:

event:
SYS_IF_DOWN
SYS_IF_UP

source:
any

severity:
any

script:
$2 == "{5757FA85-B187-42A4-981C-7443B4ECFC90}"

alarm:
none

actions:
none

options:
stop processing


Should work

Poprobujte zapustit' configure kak:

#LDFLAGS=-lmysqlclient ./configure --with-server --with-mysql --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ --build=i386-portbld-freebsd8.0

Pohoze chto eto bug v configure.

A prishlite pozalujsta config.log

Hi!

DCI object has the following attributes:

Attribute	Description
dataType	DCI data type (string, integer, etc.) represented as internal numeric code
description	DCI description
id	DCI identifier
lastPollTime	DCI last successful poll time as UNIX timestamp (number of seconds since 01.01.1970 00:00:00 UTC)
name	Parameter's name
origin	DCI origin (NetXMS agent, SNMP, etc.) represented as internal numeric code
status	DCI status (0 = active, 1 = disabled, 2 = not supported)
systemTag	DCI system tag (not available in 1.0.x versions)

So, you need lastPollTime attribute.

Please also note that there are new function called "trace", which can be very useful in debugging scripts. It takes two arguments - debug level (0 .. 9) and text, like this:

trace(1, "some message");

Text passed as second argument will appear in server's log, if given debug level less or equal current server's debug level (set by -D command line option). If debug level in trace() call set to 0, message will always be logged with INFO severity.

In 1.0.0-rc1 I have added new NXSL function FindNodeObject. It takes two arguments: current node object and ID or name of node of interest. It can be used as following:


sub main()
{
   // Search for node named "gateway"
   gw_node = FindNodeObject($node, "gateway");
   
   if (gw_node == null)
      return 0;   // No such node or access denied

   // from here, gw_node can be used in a same way as $node, for example:
   status = GetDCIValue(gw_node, FindDCIByDescription(gw_node, "Status"));

   return 1;
}

Hi all!

Version 1.0.0-rc1 is out. It's a release candidate for stable 1.0.0 branch. If it works fine, we release 1.0.0 and focus on active development of 1.1.0 branch, where lot of changes are planned. Also, preview of new Eclipse-based management console from 1.1.0 branch, compatible with current 1.0.0 branch, will be released soon.

Changes in 1.0.0-rc1 compared to 0.2.23:

- System configuration (events, SNMP traps, templates, event processing rules) can be exported and imported in XML format - this solves various problems with old NXMP files
- NXSL improvements:
   - New functions: GetDCIObject, GetInterfaceName, FindNodeObject, trace
   - Added built-in constants TRUE and FALSE
- Added support for encrypted DB passwords in netxmsd.conf
- Improved SNMPv3 support
- Fixed issues: #62, #278

Best regards,
Victor

По умолчанию на событие SNMP_LINK_DOWN аларм не создается. Надо добавить в event processing policy правило для генерации аларма по этому событию.

There are two parameters for disk space on UNIX: Disk.Free (or Disk.FreePerc) and Disk.Avail (or Disk.AvailPerc). First shows total amount of free space, including reserved blocks. Second shows free space available to non-root users - free space without reserved blocks. You should compare Disk.Avail results with df output.

Esli pri obrabotke sobitija, to dolzno rabotat' tak:

GetDCIValue($node, FindDCIByName($node, "Disk.Total(" . $6 . ")"));

Unfortunately, PocketPC version is long forgotten. Probably I could rebuild it to work with current server version, but it has very limited functionality. You can:
- Browse object tree
- Work with alarms: see list, acknowledge and terminate
- View last collected values for DCIs
- View graphs for DCIs

If such functionality is interesting for you, I could try to rebuild PocketPC client.

Victor
