This works from the NetXMS server console:

>nxwsget 127.0.0.1 http://10.9.8.7/metrics /started
/started = 1760481688751

Neither /started nor $.started work (with 'metrics' as the WS Name and using the URL above):

>nxget -D 6 127.0.0.1 'metrics:/started'

What am I doing wrong?

Installing the new agent package on a fully-patched Windows 10 machine produced this error:

The procedure entry point CRYPTO_clear_free could not be located in the dynamic link library
bin\libssl.dll

I have replaced the agent's installation directory with the [...] for clarity, but it is the correct path.

Other symbols not found:

• X509_get0_pubkey in bin\libnxagent.dll
• OPENSSL_sk_free in bin\libnetxms.dll

I wanted to use symbols in the subjects of Alert Mail in order to have a faster view of things like up/down status.  Using characters like these (▼▲) works well in Management Console notifications, but I have not been able to configure the server to send them so they appear in the subject line in e-mail clients.  Note that I am able to paste these symbols into e-mail subjects and send them with the characters intact.

I have tried changing the value of the "MailEncoding" server parameter to utf-8, but I suspect (from looking at the email.cpp source code) that I need to make use of the "MailBase64Subjects" parameter.  This parameter does not appear in the Server Configuration page in the Management Console, however, and setting it in netxmsd.conf did not seem to make a difference.

Can anyone tell me how to make this work?

Correct me if I am wrong, but I believe that the server currently connects to the agents to pull data. 

Has anyone implemented a push mechanism that would be more firewall-friendly, with all the agents connecting to the server ?

If not, would the NetXMS developers like to suggest a strategy for modifying the code to achieve this topology ?

Thanks !
