Premature Connection Close
The web server closed the connection before the user agent could receive the whole response or that the user agent got destroyed, which forces all connections to be closed immediately.
We can tune the following values to prevent this error to happen:
In the primary server
If the poller is taking too long to respond, we can increase the value of omkd_inactivity_timeout in <omk_dir>/conf/opCommon.json.
...
In this case, the SSL certificate is likely to be a local certificate authority (CA), or you might be using self-signed SSL certificates, in which case you will need to let the applications know it is OK.
In On the primary server add change the following configuration option to reflect the same as below to <omk_dir>/conf/opCommon.json in the opHA section.
| Code Block |
|---|
"opha_allow_insecure" : "1", |
You may also need to enable the below as well on the primary server:
| Code Block |
|---|
"omk_ua_insecure" : "1", |
After changing restart the daemon.
| Code Block |
|---|
systemctl restart omkd |
Connection error: there is an authorization problem
In the GUI, you observe the following error:
You should ensure that the opHA API user that is defined in opCommon.json on both the Primary/Main Primary and the poller(s) is the same user, and that this user exists in the Users.nmis table. By default the configured user is "omkapiha".
| Code Block |

"opha_api_user" : "omkapiha", |
Teapot error: error saving node to remote
in the GUI if you observe the following error:
Check the /usr/local/omk/log/opDaemon.log and if you see the following lines:
[debug] current_app_log: bad log, application_key missing
[error] NodeData::update_resource Error creating node in remote. Reason: 418 I'm a teapot
[debug] 418 I'm a teapot (0.127757s, 7.827/s)
Validate that pollers and primary have the same types set in nmis9/conf/Config.nmis for each of the following: 'nodetype_list', 'nettype_list', 'roletype_list'
An easy way to do this is using the patch_config.pl tool:
| Code Block |
|---|
/usr/local/nmis9/admin/patch_config.pl -r /usr/local/nmis9/conf/Config.nmis roletype_list /usr/local/nmis9/admin/patch_config.pl -r /usr/local/nmis9/conf/Config.nmis nettype_list /usr/local/nmis9/admin/patch_config.pl -r /usr/local/nmis9/conf/Config.nmis nodetype_list |
If mismatched then update, restart daemons (nmis9d and omkd) then rediscover poller.
