# ACL Stats
**Quickly gather access-lists stats from Cisco ASA Firewalls**
ACL Stats is a tool to help extract basic info from access-list from a
Cisco ASA Firewall, and output the information in a structured way.
The script currently collects the number of hits for each acl entry and the date of the last hit.
## Usage
First, install it via pip:
pip install acl_stats
Use it as a command line tool. You can get contextual help in the cli:
acl_stats --help
There are two main modes to pass the access-lists to the script.
### Directly from a Device
The script can connect to a device in the network and gather the informatoin needed.
A connection is made via HTTPS (same transport as ASDM), hence the firewall will need to have that method enabled.
Run ``acl_stats device --help`` to get the contextual help listing all the available parameters:
```shell
$ acl_stats device --help 02:35:23
ACL Stats
Usage: acl_stats device [OPTIONS]
Connect to a device to fech ACLs
Options:
--hostname TEXT Hostname or IP of device to connect [required]
--port INTEGER port to use when connection to a device [required]
--username TEXT username to use when connection to a device [required]
--password TEXT password to use when connection to a device [required]
--acl-name TEXT Name of target ACL [required]
--output TEXT Choose an output format: json, csv. Defaults to csv
--write-to TEXT Write the output to a file
--help Show this message and exit.
```
Here's an example:
```shell
acl_stats device --hostname 192.168.218.72 --port 443 --username cisco --password cisco --acl-name inside_in --output json
```
If you ommit the ``--write-to`` parameter, the output will be sent to ``stdout``(the terminal, usually).
## From static files
You can also run the script 'off-line', using previously extracted command outputs.
The script processes one access-list at a time for now. Here are the two commands you need to save in **separete** files:
show acess-list _name_of_acl
show access-list _name_of_acl brief
Run ``acl_stats static --help`` to get the contextual help listing all the available parameters:
```shell
$ acl_stats static --help 02:47:19
ACL Stats
Usage: acl_stats static [OPTIONS]
Use static files instead of connection to a device
Options:
--acl-file TEXT File containing the output of the show acess-list _name_
command [required]
--acl-brief TEXT File containing the output of the show acess-list _name_
brief command [required]
--output TEXT Choose an output format: json, csv. Defaults to csv
--write-to TEXT Write the output to a file
--help Show this message and exit.
```
Here's an example:
```shell
acl_stats static --acl-file acl.log --acl-brief acl_brief.log --output json --write-to acl-inside_in.csv
```
## Example Outputs
JSON Output
```json
$ acl_stats acl_stats device --hostname 192.168.218.72 --port 443 --username cisco --password cisco --acl-name inside_in --output json 02:47:23
