Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up which can resolve issues that cause many errors.
This guide will help you check for common problems that cause the log ” Azure Proxy port or host have been set but proxy type is not defined. ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: repositories, azure, repository-azure and plugins.
Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).
Overview
An Elasticsearch snapshot provides a backup mechanism that takes the current state and data in the cluster and saves it to a repository (read snapshot for more information). The backup process requires a repository to be created first. The repository needs to be registered using the _snapshot endpoint, and multiple repositories can be created per cluster. The following repository types are supported:
Repository types
| Repository type | Configuration type |
|---|---|
| Shared file system | Type: “fs” |
| S3 | Type : “s3” |
| HDFS | Type :“hdfs” |
| Azure | Type: “azure” |
| Google Cloud Storage | Type : “gcs” |
Examples
To register an “fs” repository:
PUT _snapshot/my_repo_01
{
"type": "fs",
"settings": {
"location": "/mnt/my_repo_dir"
}
}Notes and good things to know
- S3, HDFS, Azure and Google Cloud require a relevant plugin to be installed before it can be used for a snapshot.
- The setting, path.repo: /mnt/my_repo_dir needs to be added to elasticsearch.yml on all the nodes if you are planning to use the repo type of file system. Otherwise, it will fail.
- When using remote repositories, the network bandwidth and repository storage throughput should be high enough to complete the snapshot operations normally, otherwise you will end up with partial snapshots.
Log Context
Log”Azure Proxy port or host have been set but proxy type is not defined.”classname is AzureStorageSettings.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :
this.timeout = timeout;
this.maxRetries = maxRetries;
// Register the proxy if we have any
// Validate proxy settings
if (proxyType.equals(Proxy.Type.DIRECT) && ((proxyPort != 0) || Strings.hasText(proxyHost))) {
throw new SettingsException("Azure Proxy port or host have been set but proxy type is not defined.");
}
if ((proxyType.equals(Proxy.Type.DIRECT) == false) && ((proxyPort == 0) || Strings.isEmpty(proxyHost))) {
throw new SettingsException("Azure Proxy type has been set but proxy host or port is not defined.");
}
