I was trying to deploy telegraf-agent pod with the below configuration file:

```auto
[[inputs.mqtt_consumer]]
      alias = "input_mqtt_consumer_host"
      servers = [
        "mqtt://mqtt:1883"
      ]
      topics = [
        "sig/edge/gms/+/postmetrics", 
        "sig/edge/gms/+/postlocalmetrics"
      ]
      startup_error_behavior = "retry"
      json_strict = true
      tag_keys = [
        "tags_*"
      ]
      data_format = "json"
      json_name_key = "measurement"
      json_query = "metrics"
      json_string_fields = [
        "fields_*"
      ]
      json_time_format = "unix"
      json_time_key = "epochtime"
      json_timezone = "UTC"
      [inputs.mqtt_consumer.tags]
        tags_sig_host = "REPLACE_WITH_HOST_NAME"

```

The telegraf-agent pod is going to crashLoopBackOff state because it is unable to connect to MQTT endpoint.  
My telegraf agent is part of the helm chart: chart1 and MQTT is the part of helm chart: chart2.  
First chart1 will be installed and then chart2.

Below are the logs of telegraf-agent:

```

Is there a way we can ignore this error for now until MQTT pod is available and make telegraf-agent connect to MQTT once helm chart: chart2 is deployed.

I see we have the startup error behavior option here in the mqtt\_consumer plugin

> **[telegraf/plugins/inputs/mqtt\_consumer at master · influxdata/telegraf](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/mqtt_consumer#startup-error-behavior-options-)**
>
> Agent for collecting, processing, aggregating, and writing metrics, logs, and other arbitrary data. - influxdata/telegraf

I have tried setting `startup_error_behavior` to `retry` to avoid the pod going to crashLoopBackOff state and connect to MQTT once it is available:

```auto
[[inputs.mqtt_consumer]]
      startup_error_behavior = "retry"

```

But the issue still persists.

ok, I have resolved the issue.  
Initially, I was using the docker image: `telegraf:1.31.0`

The configuration `startup_error_behavior` for `mqtt_consumer` seems unsupported in the above version.

Once I updated the version to `1.32.0`, it started working.

@Rishav_Kumar_Jha I just wanted to thank you for sharing your solution with the community! Out of curiosity what are you using InfluxDB for?
