IED Logging & Monitoring issue (Syslog destination)

0
Dear supporter,   I would like to clarify if the name in the "syslog_message_key" (for Syslog destination configuration in Logging & Monitoring IED functionality) is the name of metrics or the name of fields itself.   We are able to make the configuration work with metrics log with syslog_message_key=log, but when we choose, for example, the metrics cpu with syslog_message_key=used, then the delivered message is empty. So it is when we try setting the name of the metrics instead, i.e., syslog_message_key=cpu Unfortunately, in the case of the system log, the metric name (tag) and the field name are the same, so we are not really sure.   Thanks.   Best regards, Petr

Hi Petr,  The `syslog_message_key` field should use `used` ( coming from cpu metrics data ) if you want get cpu data.  

 

The  format of “…...System.cpu” , was a json format data , e.g. 

https://docs.eu1.edge.siemens.cloud/get_started_and_operate/industrial_edge_device/operation/settings/logging%26monitoring/metrics_data.html#cpu 

The syslog output would use one of ( only one ) field  in the json data  as syslog message.   So that,  you can pick up the `used`  or `free` or others. but  only one of them.  

 

BTW,  using syslog for cpu numerical value was not a good idea.  Maybe better try influxdb, postgres, or others. 

 

{
    "irq": 0,
    "date": 1684471422.533875,
    "free": 96.296295,
    "idle": 96.296295,
    "nice": 0,
    "used": 3.7037036,
    "user": 2.4691358,

    "system": 1.2345679,
    "softirq": 0,
   ... 
}

Hi Liu, 

 

So Syslog destination is advised to be used only for log metrics from the data source System or one of the IED apps (along with the field log)?

 

Best regards,

Petr
