Helper tool get-sites.py queries application objects (HTTP and TCP Load Balancers, Proxys and Origin Pools) per namespace (or all namespaces) and creates a json file with all objects listed per site, virtual site and namespace.
The generated get-sites.json file helps to answer questions like
a) What application objects are assigned to a site or virtual site and in what namespace
b) Who created an application object
c) Are there sites that only serve origin pools
d) Are there application objects assigned to non-existent sites
-
Create a Python Virtual Environment:
python3 -m venv myenv
-
Source the new environment:
source myenv/bin/activate
-
Install required python modules:
python3 -m pip install -r requirements.txt
The script uses a F5XC API Token to access a Tenant's configuration.
-
Create an API Token for our Tenant:
Sign in to the F5 XC Console with Administrative privileges and navigate to Administration. Under 'Personal Management' select 'Credentials'. Then click 'Add Credentials' and populate the window. Make sure to select 'API Token' as the 'Credential Type' field. Save the generated API Token for the next step.
-
Define environment variables
Set environment variables with the API URL (replace tenant with your tenant name) and the generated API Token.
export f5xc_api_url="https://<tenant>.console.ves.volterra.io/api"
export f5xc_api_token="............................"
Alternatively you can set command line options instead when running the script.
$ ./get-sites.py
usage: get-sites.py [-h] [-a APIURL] [-c CSV_FILE] [-f FILE] [-n NAMESPACE] [-q] [-s SITE] [-t TOKEN] [-w WORKERS] [--diff-file DIFF_FILE] [--log-level LOG_LEVEL] [--log-stdout] [--log-file]

The generated get-sites.json is now populated with application objects per namespace and site/virtual site and can be parsed
e.g. using gron
or inspected visually.
We can now answer the questions asked in the Overview section above:
a) What application objects are assigned to a site or virtual site and in what namespace
{
"namespaces": [
"default"
],
"site": {
"alt-reg-site": {
"default": {
"loadbalancer": {
"f5dc-hello": {
"uid": "869d61fa-0b21-4482-8d8d-14ca18aa2880",
"creation_timestamp": "2022-05-10T10:11:18.812992075Z",
"deletion_timestamp": null,
"modification_timestamp": "2024-09-12T08:48:52.478785492Z",
"initializers": null,
"finalizers": [],
"tenant": "playground-wtppvaog",
"creator_class": "prism",
"creator_id": "[email protected]",
"object_index": 0,
"owner_view": null,
"labels": {}
}
},
"origin_pools": {
"mw-test": {
"uid": "3c5cb595-a78a-4edf-9c95-9d3dedbeea37",
"creation_timestamp": "2024-09-14T12:20:25.295967722Z",
"deletion_timestamp": null,

"tenant": "playground-wtppvaog",
"creator_class": "prism",
"creator_id": "[email protected]",
"object_index": 0,
"owner_view": null,
"labels": {}
}
}
},
"site_labels": {}
},
. . .
The site alt-reg-site
has a loadbalancer f5dc-hello and origin pool mw-test
assigned. Empty site_labels
for this
site alt-reg-site
indicates the site no longer exists.
b) Who created an application object
To get objects created by a specific creator (F5XC account), use gron
and grep
:
$ gron get-sites.json | grep wiget
json.site["alt-reg-site"]["default"].loadbalancer["f5dc-hello"].creator_id = "[email protected]";
json.site["alt-reg-site"]["default"].origin_pools["mw-test"].creator_id = "[email protected]";
json.site["aws-tgw-site"]["default"].loadbalancer["mw-test"].creator_id = "[email protected]";
json.site["f5dc-wdc-1-sat-cluster-1"]["default"].origin_pools["f5dc-cluster1-iperf3"].creator_id = "[email protected]";
json.site["f5dc-wdc-1-sat-cluster-1"]["default"].origin_pools["f5dc-hello"].creator_id = "[email protected]";
json.site["f5dc-wdc-2-sat-cluster-2"]["default"].loadbalancer["f5dc-cluster2-iperf3"].creator_id = "[email protected]";
json.site["f5dc-wdc-2-sat-cluster-2"]["default"].loadbalancer["f5dc-hello-cluster2"].creator_id = "[email protected]";
json.site["mw-ce1"]["default"].origin_pools["mwce1-alpine1"].creator_id = "[email protected]";
To narrow the search down to a single site, use:
$ gron get-sites.json | grep wiget | grep f5dc-wdc-1-sat-cluster-1
json.site["f5dc-wdc-1-sat-cluster-1"]["default"].origin_pools["f5dc-cluster1-iperf3"].creator_id = "[email protected]";
json.site["f5dc-wdc-1-sat-cluster-1"]["default"].origin_pools["f5dc-hello"].creator_id = "[email protected]";
c) Are there sites that only serve origin pools
After collecting all configuration objects into the sites dictionary, the script walks the dictionary and checks
for sites that have only load balancers and stores the result as a separate list in sites under sites_with_only_origin_pools
.
To extract that list, look at the written get-sites.json file or use gron
and grep
:
$ gron get-sites.json|grep with_only
json.sites_with_only_origin_pools = [];
json.sites_with_only_origin_pools[2] = "ce-on-k8s-aswin-aws";
json.sites_with_only_origin_pools[3] = "ce-rseries-demo";
json.sites_with_only_origin_pools[4] = "crt-ce05";
json.sites_with_only_origin_pools[5] = "auto-az-crt";
json.sites_with_only_origin_pools[6] = "cosmos-ce-hyd-cloud";
json.sites_with_only_origin_pools[9] = "multitunnel-aws";
json.sites_with_only_origin_pools[10] = "auto-aws-crt";
json.sites_with_only_origin_pools[11] = "ce-rseries-integration";
d) Are there application objects assigned to non-existent sites
Look through the generated get-sites.json
file for empty site_labels. See answer a)
above.
This tool provides a comparison function to compare page information. The steps to compare site information are as follows:
- Run query for
siteA
and write data toout_site_a.json
./get-sites.py -f `./out_site_a_json` -q -s `siteA` --log-level INFO --log-stdout
- Run query for
siteB
and compare tositeA
data./get-sites.py -f `./out_site_b.json` -q -s `siteB` --diff-file `./ou_site_a_json` --log-level INFO --log-stdout
- Output
2024-10-22 16:11:09,129 - INFO - 1 site and 0 virtual site written to ./get-sites-diff-b.json 2024-10-22 16:11:09,129 - INFO - compare started with data from get-sites-diff-a.json and current api run... 2024-10-22 16:11:09,129 - INFO - 1 site and 0 virtual site read from ./get-sites-diff-a.json 2024-10-22 16:11:09,129 - INFO - compare done with results: {'os': True, 'cpu': True, 'memory': True, 'network': [True]}
Above output shows there are no differences for hardware info items cpu, memory and network
This tool offers the function to create a CSV inventory file. This file can be read in and further processed by applying filters to the generated data.
- Run query for specif site or specific namespace or for all data
./get-sites.py -f ./get-sites-all-ns.json -q --log-level INFO --log-stdout
- Run create CSV inventory file function
./get-sites.py -f ./get-sites-all-ns.json -c inventory.csv --log-level INFO --log-stdout
