 * [SysFlow](https://sysflow.io) SysFlow is a cloud-native system telemetry framework that focuses on data abstraction, behavioral analytics, and noise reduction. At its core, SysFlow exposes a compact open telemetry format that records workload behaviors by connecting event and flow representations of process control flows, file interactions, and network communications. The resulting abstraction encodes a graph structure that enables provenance reasoning on host and container environments, and fast retrieval of security-relevant information.

+* [StackRox](https://stackrox.io) is the industry’s first Kubernetes-native security platform enabling organizations to build, deploy, and run cloud-native applications securely. The platform works with Kubernetes environments and integrates with DevOps and security tools, enabling teams to operationalize and secure their supply chain, infrastructure, and workloads. StackRox aims to harness containerized applications’ development speed while giving operations and security teams greater context and risk profiling. StackRox leverages cloud-native principles and declarative artifacts to automate DevSecOps best practices.

-### Developing
+## Developing

 Falco is designed to be extensible such that it can be built into cloud-native applications and infrastructure.

 Falco has a [gRPC](https://falco.org/docs/grpc/) endpoint and an API defined in [protobuf](https://github.com/falcosecurity/falco/blob/master/userspace/falco/outputs.proto).
 The Falco Project supports various SDKs for this endpoint.

+# --- [Description]
+#
+# This is an index that controls the dimension of the syscall buffers.
+# The syscall buffer is the shared space between Falco and its drivers where all the syscall events
+# are stored.
+# Falco uses a syscall buffer for every online CPU, and all these buffers share the same dimension.
+# So this parameter allows you to control the size of all the buffers!
+#
+# --- [Usage]
+#
+# You can choose between different indexes: from `1` to `10` (`0` is reserved for future uses).
+# Every index corresponds to a dimension in bytes:
+#
+# [(*), 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB]
+#   ^    ^     ^     ^     ^     ^      ^      ^       ^       ^       ^
+#   |    |     |     |     |     |      |      |       |       |       |
+#   0    1     2     3     4     5      6      7       8       9       10
+#
+# As you can see the `0` index is reserved, while the index `1` corresponds to
+# `1 MB` and so on.
+#
+# These dimensions in bytes derive from the fact that the buffer size must be:
+# (1) a power of 2.
+# (2) a multiple of your system_page_dimension.
+# (3) greater than `2 * (system_page_dimension)`.
+#
+# According to these constraints is possible that sometimes you cannot use all the indexes, let's consider an
+# example to better understand it:
+# If you have a `page_size` of 1 MB the first available buffer size is 4 MB because 2 MB is exactly
+# `2 * (system_page_size)` -> `2 * 1 MB`, but this is not enough we need more than `2 * (system_page_size)`!
+# So from this example is clear that if you have a page size of 1 MB the first index that you can use is `3`.
+#
+# Please note: this is a very extreme case just to let you understand the mechanism, usually the page size is something
+# like 4 KB so you have no problem at all and you can use all the indexes (from `1` to `10`).
+#
+# To check your system page size use the Falco `--page-size` command line option. The output on a system with a page
+# size of 4096 Bytes (4 KB) should be the following:
+#
+# "Your system page size is: 4096 bytes."
+#
+# --- [Suggestions]
+#
+# Before the introduction of this param the buffer size was fixed to 8 MB (so index `4`, as you can see
+# in the default value below).
+# You can increase the buffer size when you face syscall drops. A size of 16 MB (so index `5`) can reduce
+# syscall drops in production-heavy systems without noticeable impact. Very large buffers however could
+# slow down the entire machine.
+# On the other side you can try to reduce the buffer size to speed up the system, but this could
+# increase the number of syscall drops!
+# As a final remark consider that the buffer size is mapped twice in the process' virtual memory so a buffer of 8 MB
+# will result in a 16 MB area in the process virtual memory.
+# Please pay attention when you use this parameter and change it only if the default size doesn't fit your use case.
