Hi,

Yes, I think we will use SSH more. Some automation with SSH is already possible - like execute command as a reaction for an event for example, or execute command from script and process output. One obvious direction for improvement is to introduce concept of SSH session to NXSL scripts and allow execution of multiple commands within single session.

I just checked and there is a bug in SSH polling code - server attempts to connect with empty user name and password if nothing is set. We will fix it until next patch release.

For disabling SSH polling you can use NXSL method enableSsh on node object - either add it to configuration poll hook or run once script that will enumerate all nodes and set SSH flag to false. Also, if you are not using SSH functionality, you can disable SSH subagent on server's local agent and on proxy nodes.

Hi,

looks like nobody checked that client proxy actually compiles. Do you really use it? If not, just remove --with-client-proxy from configure (we will fix compilation anyway though).

Hi,

version 4.1 attempts to detect SSH availability during configuration poll. Most likely other switches just don't report failed SSH login attempts, or they have valid credentials. If you don't need SSH access to problematic switches you can disable SSH polling in node properties on "Polling" page.

Hi,

it's possible to some degree. Few options here:

1. Create circular status map - you can define root object, and status map will show sub-objects and their statuses as sunburst diagram. However, drilldown action is hardcoded and will open list of active alarms for selected object.

2. Create network map - you can place any object on a map, and as drilldown you can set other map or dashboard. This will not be sunburst diagram however - although you can represent objects in some logical layout.

Not each output of powershell begins with empty line, only this specific command does. You can filter output further, probably from powershell itself as well, but I don't know how (not using it). However, command line pipe should work as well (I assume you are interested in line with version number):


ExternalParameterShellExec = ExchangePatchNumber:pwsh -Command { Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo} } | find "ExSetup.exe"

Hi,

I just fixed this issue, fix will be included into next patch release. Current workaround is to press refresh if overview is not shown for too long.

Hi,

can you check log on proxy agent around time when SYS_SSH_UNREACHABLE generated? Make sure you have debug level 6 or more for tag "ssh".

Yes, only first line is taken as value of external parameter. You have to format output in your script so it return required value in first line.

Hi,

you can try to manually add column tt_row_number to table dct_threshold_instances (integer not null, set it to 0 if you have any records in dct_threshold_instances table), then you can try to run upgrade with -X option (it will ignore upgrade errors and continue). One of next upgrade procedures will try to rename row_number to tt_row_number, so you should end up with correct schema.
Make sure you have database snapshot or backup before trying this, and watch for possible other errors, because with -X DB manager would not stop at them anymore.

Hi,

you should use $$ to insert $ into command, as it is start of command argument ($1, $2, etc.).

Is it mean for authenticating NetXMS users, or for use with SSH connections from NetXMS to devices? Because latter is already implemented for some time.

Hi,

yes, it can be done, but it will take some time to move all strings to message files. I will update on progress.

For L2 maps server consider any node without bridge capability to be end node. Bridge capability determined by attempting to access BRIDGE-MIB during configuration poll (specifically OIDs .1.3.6.1.2.1.17.1.1.0 and .1.3.6.1.2.1.17.1.2.0).
