 For effortless visualization of the RouterOS metrics exported to Prometheus, MKTXP comes with a dedicated [Grafana dashboard](https://grafana.com/grafana/dashboards/13679):

+## Advanced features
+While most of the [mktxp options](https://github.com/akpw/mktxp#getting-started) are self explanatory, some might require a bit of a context.
+
+### Remote DHCP resolution
+When gathering various IP address-related metrics, mktxp automatically does DHCP resolution whenever available. In many cases however, the exported devices does not have this information locally and instead rely on a central DHCP server. The exported metrics thus operates with IP / MAC addresses which reduces level of readability and usefulness. In case this information is needed, mktxp supports remote DHCP server calls via this option:
+```
+remote_dhcp_entry = None        # An MKTXP entry for remote DHCP info resolution in capsman/wireless
+```
+`MKTXP entry` in this context can be any other mktxp.conf entry, and for sole the purpose of providing the DHCP info does not even need to be enabled 
+
+### Connections stats
+
+```
+connection_stats = False        # Open IP connections metrics 
+```
+
+### Parallel routers fetch
+
+```
+fetch_routers_in_parallel = False   # Set to True if you want to fetch multiple routers parallel
+    max_worker_threads = 5              # Max number of worker threads that can fetch routers (parallel fetch only)
+    max_scrape_duration = 10            # Max duration of individual routers' metrics collection (parallel fetch only)
+    total_max_scrape_duration = 30      # Max overall duration of all metrics collection (parallel fetch only)
+```
