Display Apache JMeter logs, in Grafana using the Logs Panel and InfluxDB as data source - jmeter

Question

Objective : To Use Grafana log panel to display Apache JMeter Logs for an execution, using InfluxDB Backend Listener.
apache-jmeter-5.5
influxdb-1.8.10-1
grafana-8.5.0
I am using InfluxDBBackendListenerClient for my JMeter tests and grafana to display the the test metrics data into the dashboard.
I want to use the Grafana Logs Panel, to fetch Apache-Jmeter Execution Data,
I had accomplished this couple of years back and the log panel use to look like the below image:
Unfortunately, I don't have that dashboard and want to integrate the logs to my current dashboard.My Current logs dashboard looks like this below:
Influx Query: I have used the below mentioned influx query, I know something is wrong with the query.
I would really appreciate is anyone can help me resolve this query and aid me to get a dashboard in similar format as the first image,

JMeter's Backend listener doesn't send Apache JMeter logs, here is the list of the metrics which are supported as of JMeter 5.5
15.1.1 Thread/Virtual Users metrics
Thread metrics are the following:
<rootMetricsPrefix>test.minAT
Min active threads
<rootMetricsPrefix>test.maxAT
Max active threads
<rootMetricsPrefix>test.meanAT
Mean active threads
<rootMetricsPrefix>test.startedT
Started threads
<rootMetricsPrefix>test.endedT
Finished threads
15.1.2 Response times metrics
Response related metrics are the following:
<rootMetricsPrefix><samplerName>.ok.count
Number of successful responses for sampler name
<rootMetricsPrefix><samplerName>.h.count
Server hits per seconds, this metric cumulates Sample Result and Sub results (if using Transaction Controller, "Generate parent sampler" should be unchecked)
<rootMetricsPrefix><samplerName>.ok.min
Min response time for successful responses of sampler name
<rootMetricsPrefix><samplerName>.ok.max
Max response time for successful responses of sampler name
<rootMetricsPrefix><samplerName>.ok.avg
Average response time for successful responses of sampler name.
<rootMetricsPrefix><samplerName>.ok.pct<percentileValue>
Percentile computed for successful responses of sampler name. There will be one metric for each calculated value.
<rootMetricsPrefix><samplerName>.ko.count
Number of failed responses for sampler name
<rootMetricsPrefix><samplerName>.ko.min
Min response time for failed responses of sampler name
<rootMetricsPrefix><samplerName>.ko.max
Max response time for failed responses of sampler name
<rootMetricsPrefix><samplerName>.ko.avg
Average response time for failed responses of sampler name.
<rootMetricsPrefix><samplerName>.ko.pct<percentileValue>
Percentile computed for failed responses of sampler name. There will be one metric for each calculated value.
<rootMetricsPrefix><samplerName>.a.count
Number of responses for sampler name (sum of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.sb.bytes
Sent Bytes
<rootMetricsPrefix><samplerName>.rb.bytes
Received Bytes
<rootMetricsPrefix><samplerName>.a.min
Min response time for responses of sampler name (min of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.max
Max response time for responses of sampler name (max of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.avg
Average response time for responses of sampler name (avg of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.pct<percentileValue>
Percentile computed for responses of sampler name. There will be one metric for each calculated value. (calculated on the totals for OK and failed samples)
In order to be able to see JMeter log in Grafana you need to add it somehow to InfluxDB, I can think of the following options:
Periodically read it using JSR223 Test Elements and sending to InfluxDB HTTP endpoint using "normal" JMeter HTTP Request sampler
Come up with your own implementation of the Backend Listener which will be sending log file entries along with other metrics
