+# PYSNP debug mode (internal)
+
+During the on-calls and escalations, it might be helpful to understand low-levels details that are happening on SNMP protocol side. For that we are using `debug logger` from `pysnmp lib`.
+
+
+List of available debug modes:
+* io
+* dsp
+* msgproc
+* secmod
+* mibbuild
+* mibview
+* mibinstrum
+* acl
+* proxy
+* app
+* all
+
+
+## docker-compose
+
+Add on `.env` file `PYSNMP_DEBUG` variable and specify debug modes in comma-separated format:
+
+```
+PYSNMP_DEBUG=dsp,msgproc,io
+```
+
+## k8s
+
+Add on top level of `values.yaml` file `pysnmpDebug` variable and specify debug modes (using comma-separated format):
+
+```
+pysnmpDebug: "dsp,msgproc,io"
+```
