NimbostratusASM Export JSON - size Limit ?
Hello,
I'm trying to export an ASM Policy in json format through API
I'm using theses Steps:
- Start the export:
https://{hostname}/mgmt/tm/asm/tasks/export-policy
{
"format": "json",
"filename": "exported_file.json",
"minimal": true,
"policyReference": {
"link": "https://localhost/mgmt/tm/asm/policies/{policyID}"
}
}
- Waiting for the export to end
- Download The export
https://{hostname}//mgmt/tm/asm/file-transfer/downloads/exported_file.json
The downloaded file is imcomplete, truncated and not usable if I try to import it
Not sure if it the cause but the size of the file is 1Mo
While if I export it manually through GUI it's 1,3Mo sized
Also I've already modified the max_json_policy_size to 5Mo in the
Security ›› Options : Application Security : Advanced Configuration : System Variables
Because I had issues when importing the same policie.
Is there some kind of limit for export ?

Hi IVD,
I found two previous threads about it.
They wrote that the file download size limit is 1024kb, and it can be solved using content-range.
API Calls to F5 limited to 1024 KB download | DevCentral

IVDHello Thanks for you reply,
I ended up at the same conclusion,
F5 Bigip API cannot manage large file and
I needs to upload or download file in 1024kb chunks parts.
Haven't find how to do it with ansible,
so I did it in shellwith:
url= "https://{{ inventory_hostname }}/mgmt/tm/asm/file-transfer/downloads/{{ export_filename }}"
output="{{ export_filename }}"
taille={{ task_status.json.result.fileSize }}
chunk=1048576
debut=0
fin=1048575
while [ $debut -lt $taille ]; do
if [ $fin -ge $taille ]; then
fin=$(($taille - 1))
fi
curl -s -H "Content-Range: $debut-$fin/$chunk" -o /tmp/partie_$debut -H "Content-Type: application/json" -H "X-F5-Auth-Token: {{ extracted_auth_token }}" $url
debut=$(($debut + $chunk))
fin=$(($fin + $chunk))
done
cat /tmp/partie_* > {{ dest_dir }}/{{ export_filename }}
if someone else have a better way to do it, I'm interrested...
