  We were trying to integrate Spring Cloud Gateway (SCG) on Kubernetes with HashiCorp. We followed the steps mentioned in vault   documentation . We were able to bring up vault and vault injector but SCG pods were stuck in init state. Found following error in SCG application pod vault-agent-init container logs: NAME READY STATUS RESTARTS AGE scg-0 0/2 Init:0/1 0 9h vault-0 1/1 Running 0 10h vault-agent-injector-5c89c7dfc5-n2v6v 1/1 Running 0 20h Cgo: disabled Log Level: info Version: Vault v1.8.4 Version Sha: 925bc650ad1d997e84fbb832f302a6bfe0105bbb 2022-09-30T16:24:28.007Z [INFO] sink.server: starting sink server 2022-09-30T16:24:28.007Z INFO creating watcher 2022-09-30T16:25:28.008Z [ERROR] auth.handler: error authenticating: error="context deadline exceeded" backoff=1s To verify that vault injector was connecting to right vault instance, we verified init agent config using below kubectl command: kubectl exec -it scg-0 -c va...

  This blog is about connection reset error we received while connecting from Boomi atom to remote sftp. This issue can occur for any client connecting to a remote sftp server. The sftp server we were trying to connect was old sftp server and it has been used in many integrations. We haven’t faced reset issue for other integrations flow except this new one. So, we first suspected that there was something wrong with the process itself. We looked closely at the process. The process has multiple processes – one main process and multiple child processes. Main process checks for availability of files and child processes transfer files to Boomi atoms for further processing. The first main process and few child processes succeed always but last few process would fail always (usually after processing 7 or 8 files). We tweaked the process to drill down the issue. Here are few thing we tried: Disabled all other processes that connect to the same sftp server. Issue still occurred. We checked ...

There are couple of ways to monitor Kafka consumer Lag. There is an open source project called   Apache Burrow   which has lot of features and easy to set up. It filters out lot of false positives too. If there are an limitations of using it in your project, we can write bash scripts using Kafka consumer utility which ships with Kafka. We have written one such script. If you are interested,   please check it out here .
