1.4 List full details for specific pod names (labels, images, ports, volumes, events, and more).

Command:

kubectl describe pods <pod_name> -n <namespace>

Example:

cisco@brusmi-master1:~$ kubectl describe pods smf-service-n0-0 -n smf-data

smf-service-n0-0    <<< POD name

smf-data            <<< Namespace

2. k8s Logs and Full Core

2.1 Get Container name for specific pod:

Command:

kubectl describe pods <pod_name> -n <namespace> | grep Containers -A1

Example:

cisco@brusmi-master1:~$ kubectl describe pods smf-service-n0-0 -n smf-data | grep Containers -A1

Containers:

smf-service:

--

ContainersReady   True

PodScheduled      True

2.2 Look for logs when a pod crash is observed on Kubernetes:

Command:

kubectl get pods -n <namespace> | grep -v Running

Example:

cisco@brusmi-master1:~$ kubectl get pods -n smf-data | grep -v Running

NAME                                               READY   STATUS             RESTARTS   AGE

smart-agent-smf-data-ops-center-6667dcdd65-2h7nr   0/1     Evicted            0          5d23h

smf-service-n0-0                                   0/1     CrashLoopBackOff   2          6h12m

2.3 Verify if coredumps were generated:

Command:

ls -lrt /var/lib/systemd/coredump/

Example:

cisco@brusmi-master1:~$ ls -lrt /var/lib/systemd/coredump/

total 0

Note: The core file shall be generated in /var/lib/systemd/coredump/ path in the respective VM. The core is also available on the TAC Dashboard.

3. Create TAC-Debug on CEE

3.1 Login into cee Ops-Center from Master k8s:

cisco@brusmi-master1:~$ kubectl get namespace

NAME              STATUS   AGE

cee-cee           Active   5d3h

default           Active   5d3h

kube-node-lease   Active   5d3h

kube-public       Active   5d3h

kube-system       Active   5d3h

lfs               Active   5d3h

nginx-ingress     Active   5d3h

smf-data          Active   5d3h

smi-certs         Active   5d3h

smi-vips          Active   5d3h

cisco@brusmi-master1:~$ ssh -p 2024 admin@$(kubectl get svc -n cee-cee | grep ^ops-center | awk '{print $3}')

admin@10.102.44.219's password:

Welcome to the cee CLI on brusmi/cee

admin connected from 192.x.0.1 using ssh on ops-center-cee-cee-ops-center-79cf55b49b-6wrh9

[brusmi/cee] cee#

Note: In the example mentioned previously, the CEE namespace is “cee-cee”. You must replace this name in case you require it.

3.2 Generate the TAC package ID to reference collection files retrieved:

Command:

tac-debug-pkg create from <Start_time> to <End_time>

Example:

[brusmi/cee] cee# tac-debug-pkg create from 2020-06-08_14:00:00 to 2020-06-08_15:00:00

response : Tue Jun  9 00:22:17 UTC 2020 tac-debug pkg ID : 1592948929

Also, you can include additional filters like namespace or pod_name as follows:

Command:

tac-debug-pkg create from <Start_time> to <End_time> logs-filter { namespace <namespace> pod_name <pod_name> }

Example:

[brusmi/cee] cee# tac-debug-pkg create from 2020-06-08_14:00:00 to 2020-06-08_15:00:00 logs-filter { namespace smf-data pod_name cache-pod-0 }

response : Tue Jun  9 00:28:49 UTC 2020 tac-debug pkg ID : 1591662529

Note: It is recommended to generate a tac package ID for a slot period of time (1 hr or max 2 hrs).

3.3 Display the status of each service:

[brusmi/cee] cee# tac-debug-pkg status

response : Tue Jun  9 00:28:51 UTC 2020

Tac id: 1591662529

Note: If there is no available disk space, please remove old debug files.

[brusmi/cee] cee# tac-debug-pkg create from 2020-06-08_09:00:00 to 2020-06-08_10:00:00 logs-filter { namespace smf-data }

[brusmi/cee] cee# tac-debug-pkg delete tac-id 1591662529

3.4 Create a TAC Debug ID to gather Metrics only:

[nyucs504-cnat/global] cee# tac-debug-pkg create from 2021-02-24_12:30:00 to 2021-02-24_14:30:00 cores false logs false cfg false stats false

response : Wed Feb 24 19:39:49 UTC 2021 tac-debug pkg ID : 1614195589

4. Download TAC Debug

Currently, there are three different options to download the TAC Debug from CEE:

4.1 SFTP from Master VIP (less recommended, it takes a long).

4.1.1 Get the URL to download the logs gathered on tac package ID :

Command:

kubectl get ingress -n <namespace> | grep show-tac

Example:

cisco@brusmi-master1:~$ kubectl get ingress -n cee-cee | grep show-tac

show-tac-manager-ingress                show-tac-manager.cee-cee-smi-show-tac.192.168.208.10.xxx.x             80, 443   5d4h

4.1.2 Compress and get the tac-debug file from show-tac-manager pod:

a. Get the ID of the show-tac pod.

Command:

kubectl get pods -n <namespace> | grep show-tac

Example:

cisco@brusmi-master1:~$ kubectl get pods -n cee-cee | grep show-tac

show-tac-manager-85985946f6-bflrc 2/2 Running 0 12d

b. Run exec command in show-tac pod, and compress the TAC Debug logs.

Command:

kubectl exec -it -n <namespace> <pod_name> bash

Example:

cisco@brusmi-master1:~$ kubectl exec -it -n cee-cee show-tac-manager-85985946f6-bflrc bash

Defaulting container name to show-tac-manager.

Use 'kubectl describe pod/show-tac-manager-85985946f6-bflrc -n cee-cee' to see all of the containers in this pod.

4.1.3 Copy the file to /tmp directory on Master VIP:

Command:

kubectl cp <namespace>/<show-tac_pod_name>:/home/tac/<file_name.tar.gz> /tmp/<file_name.tar.gz>

Example:

cisco@brusmi-master1:~$ kubectl cp cee-cee/show-tac-manager-85985946f6-bflrc:/home/tac/tac-debug_1591662529.tar.gz /tmp/tac-debug_1591662529.tar.gz

Defaulting container name to show-tac-manager.

4.1.4 Transfer file via sftp from Master VIP.

4.2 Download the TAC Debug with wget command (macOS/Ubuntu).

4.2.1 Get show-tac link from "k8s get ingress" output:

cisco@brusmi-master1:~$ kubectl get ingress -n cee-cee | grep show-tac

show-tac-manager-ingress                show-tac-manager.cee-cee-smi-show-tac.192.168.208.10.xxx.x             80, 443   5d4h

4.2.2 Enter the wget command from your PC terminal:

wget -r -np https://show-tac-manager.cee-cee-smi-show-tac.192.168.208.10.xxx.x/tac/

<tac-id>/ --no-check-certificate --http-user=<NTID_username>

5. Collect logs from CEE for all the SMF PODs

5.1 Login into smf-dataOps-Center from Master k8s:

cisco@brusmi-master1:~$ ssh -p 2024 admin@$(kubectl get svc -n smf-data | grep ^ops-center | awk '{print $3}')

admin@10.103.164.204's password:

Welcome to the smf CLI on brusmi/data

admin connected from 192.x.0.1 using ssh on ops-center-smf-data-ops-center-7fbb97d9c9-tx7qd

5.2 Confirm if “logging level application” is enabled:

[brusmi/data] smf# show running-config | i logging

logging level application debug

logging level transaction debug

logging level tracing debug

logging name infra.config.core level application debug

logging name infra.config.core level transaction debug

logging name infra.config.core level tracing debug

logging name infra.message_log.core level application debug

logging name infra.message_log.core level transaction debug

logging name infra.resource_monitor.core level application off

logging name infra.rest_server.core level application debug

5.3 Login into cee Ops-Center from Master k8s:

cisco@brusmi-master1:~$ ssh -p 2024 admin@$(kubectl get svc -n cee-cee | grep ^ops-center | awk '{print $3}')

admin@10.102.44.219's password:

Welcome to the cee CLI on brusmi/cee

admin connected from 192.x.0.1 using ssh on ops-center-cee-cee-ops-center-79cf55b49b-6wrh9

[brusmi/cee] cee#

Note: In the example mentioned previously, the CEE namespace is “cee-cee”. You must replace this name in case you require it.

5.4 Tail the logs of all the SMF PODs that start with “smf-“ (smf-nodemgr, smf-protocol, smf-rest , smf-service, smf-udp-proxy). Collect the logs for a few seconds, and use Ctrl+C to stop data collection:

[brusmi/cee] cee# cluster logs ^smf- -n smf-data

error: current-context must exist in order to minify

Will tail 5 logs...
