+          notices within Derivative Works that You distribute, alongside

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

-# 📈 Aralez Prometheus Metrics Reference
-
-This document outlines Prometheus metrics for the [Aralez](https://github.com/sadoyan/aralez) reverse proxy.
-These metrics can be used for monitoring, alerting and performance analysis.
-
-Exposed to `http://config_address/metrics`
-
-By default `http://127.0.0.1:3000/metrics`
-
-# 📊 Example Grafana dashboard during stress test :

-
-## 🛠️ Prometheus Metrics
-
-### 1. `aralez_requests_total`
-
-- **Type**: `Counter`
-- **Purpose**: Total amount requests served by Aralez.
-
-**PromQL example:**
-
-```promql
-rate(aralez_requests_total[5m])
-```
-
----
-
-### 2. `aralez_errors_total`
-
-- **Type**: `Counter`
-- **Purpose**: Count of requests that resulted in an error.
-
-**PromQL example:**
-
-```promql
-rate(aralez_errors_total[5m])
-```
-
----
-
-### 3. `aralez_responses_total{status="200"}`
-
-- **Type**: `CounterVec`
-- **Purpose**: Count of responses by HTTP status code.
-
-**PromQL example:**
-
-```promql
-rate(aralez_responses_total{status=~"5.."}[5m]) > 0
-```
-
-> Useful for alerting on 5xx errors.
-
----
-
-### 4. `aralez_response_latency_seconds`
-
-- **Type**: `Histogram`
-- **Purpose**: Tracks the latency of responses in seconds.
-
-**Example bucket output:**
-
-```prometheus
-aralez_response_latency_seconds_bucket{le="0.01"}  15
-aralez_response_latency_seconds_bucket{le="0.1"}   120
-aralez_response_latency_seconds_bucket{le="0.25"}  245
-aralez_response_latency_seconds_bucket{le="0.5"}   500
-...
-aralez_response_latency_seconds_count  1023
-aralez_response_latency_seconds_sum    42.6
-```
-
-| Metric                  | Meaning                                                       |
-|-------------------------|---------------------------------------------------------------|
-| `bucket{le="0.1"} 120`  | 120 requests were ≤ 100ms                                     |
-| `bucket{le="0.25"} 245` | 245 requests were ≤ 250ms                                     |
-| `count`                 | Total number of observations (i.e., total responses measured) |
-| `sum`                   | Total time of all responses, in seconds                       |
-
-### 🔍 How to interpret:
-
-- `le` means “less than or equal to”.
-- `count` is total amount of observations.
-- `sum` is the total time (in seconds) of all responses.
-
-**PromQL examples:**
-
-🔹 **95th percentile latency**
-
-```promql
-histogram_quantile(0.95, rate(aralez_response_latency_seconds_bucket[5m]))
-
-```
-
-🔹 **Average latency**
-
-```promql
-rate(aralez_response_latency_seconds_sum[5m]) / rate(aralez_response_latency_seconds_count[5m])
-```

 **This means:**
 
 - Sticky sessions are disabled globally. This setting applies to all upstreams. If enabled all requests will be 301 redirected to HTTPS.
 - HTTP to HTTPS redirect disabled globally, but can be overridden by `to_https` setting per upstream.
+- All upstreams will receive custom headers : `X-Forwarded-Proto:https` and `X-Forwarded-Port:443`
+- Additionally, myhost.mydomain.com with path `/` will receive custom headers : `X-Another-Header:Hohohohoho` and `X-Something-Else:Foobar`
 - Requests to each hosted domains will be limited to 10 requests per second per virtualhost.
     - Requests limits are calculated per requester ip plus requested virtualhost.
     - If the requester exceeds the limit it will receive `429 Too Many Requests` error.
     - Optional. Rate limiter will be disabled if the parameter is entirely removed from config.
+- Requests to `myhost.mydomain.com/` will be limited to 20 requests per second.
 - Requests to `myhost.mydomain.com/` will be proxied to `127.0.0.1` and `127.0.0.2`.
 - Plain HTTP to `myhost.mydomain.com/foo` will get 301 redirect to configured TLS port of Aralez.
 - Requests to `myhost.mydomain.com/foo` will be proxied to `127.0.0.4` and `127.0.0.5`.
+- Requests to `myhost.mydomain.com/.well-known/acme-challenge` will be proxied to `127.0.0.1:8001`, but healthcheks are disabled.
 - SSL/TLS for upstreams is detected automatically, no need to set any config parameter.
     - Assuming the `127.0.0.5:8443` is SSL protected. The inner traffic will use TLS.
     - Self-signed certificates are silently accepted.

+## 🚀 Aralez, Nginx, Traefik performance benchmark
+
+This benchmark is done on 4 servers. With CPU Intel(R) Xeon(R) E-2174G CPU @ 3.80GHz, 64 GB RAM.
+
+1. Sever runs Aralez, Traefik, Nginx on different ports. Tuned as much as I could .
+2. 3x Upstreams servers, running Nginx. Replying with dummy json hardcoded in config file for max performance.
+
+All servers are connected to the same switch with 1GB port in datacenter , not a home lab. The results:
+![Aralez](https://raw.githubusercontent.com/sadoyan/aralez/refs/heads/main/assets/bench.png)
+
+The results show requests per second performed by Load balancer. You can see 3 batches with 800 concurrent users.
+
+1. Requests via http1.1 to plain text endpoint.
+2. Requests to via http2 to SSL endpoint.
+3. Mixed workload with plain http1.1 and htt2 SSL.
