When installing my LXC app on IOx I receive the following message: { "description": "Invalid Archive file: [Errno 28] No space left on device", "errorcode": -1, "message": "Invalid Archive file" } This got me wondering whether old images are being retained on the file system. I believe they are. If I issue: du -h /software/caf/work/layers ...then this shows that 472M used. At this point, I have no app installed, so this must be old LXC image layer info. Can you please advise on a supported means of tidying up the disk? Thanks. ... View more

When uploading files into /data/appdata via the IOx Local Manager, I find that my app cannot read them due to privileges. I'm also unable to modify the privileges from within the LXC. Here are what the files look like from within the LXC: / # ls -al data/appdata/caf_cert.pem -rw-------    1 nobody   nobody        1459 Mar 26 08:44 data/appdata/caf_cert.pem Please advise on how files may be uploaded such that they are readable. ...

Hi there, I've configured my CAF hosted application to provide metrics for the purposes of Visualization. My app's summary shows a "Visualize" button which, when clicked, displays an empty screen as per: If you zoom in on that image you can see two horizontal bars. I believe my app is correctly sending data as, before I had configured certificates, the above screen informed me that no data had been received. Now it doesn't, it is just blank. Could you tell me what this may signify and how I may be able to further diagnose what's going on? Here is a sample of the metadata content I send: {   "datapoints" : {    "lora-server.downlink-packets-rx,lora-server.downlink-packets-tx" : {    "units" : "Pkts" ,    "max" : "" ,    "displayName" : "Downlink Rx,Tx" ,    "graphType" : "bar" ,    "min" : ""    } ,    "lora-server.uplink-packets-rx,lora-server.uplink-packets-tx" : {    "units" : "Pkts" ,    "max" : "" ,    "displayName" : "Uplink Rx,Tx" ,    "graphType" : "bar" ,    "min" : ""    } ,    "lora-server.messages-appended/lora-server.uplink-packets-rx" : {    "units" : "Msgs" ,    "max" : "100" ,    "displayName" : "Valid" ,    "graphType" : "gauge" ,    "min" : "0"    } ,    "lora-server.messages-cannot-append/lora-server.uplink-packets-rx" : {    "units" : "Msgs" ,    "max" : "100" ,    "displayName" : "Invalid" ,    "graphType" : "gauge" ,    "min" : "0"    } ,    "lora-server.incorrect-fcnt/lora-server.uplink-packets-rx" : {    "units" : "Msgs" ,    "max" : "100" ,    "displayName" : "Bad FCnt" ,    "graphType" : "gauge" ,    "min" : "0"    } ,    "lora-server.incorrect-mic/lora-server.uplink-packets-rx" : {    "units" : "Msgs" ,    "max" : "100" ,    "displayName" : "Bad MIC" ,    "graphType" : "gauge" ,    "min" : "0"    }   } } ...and a sample of the data: {   "lora-server.messages-cannot-append/lora-server.uplink-packets-rx": [     {       "value": "0"     }   ],   "lora-server.incorrect-fcnt/lora-server.uplink-packets-rx": [     {       "value": "0"     }   ],   "lora-server.uplink-packets-rx,lora-server.uplink-packets-tx": [     {       "value": "2"     },     {       "value": "2"     }   ],   "lora-server.incorrect-mic/lora-server.uplink-packets-rx": [     {       "value": "0"     }   ],   "lora-server.downlink-packets-rx,lora-server.downlink-packets-tx": [     {       "value": "0"     },     {       "value": "0"     }   ],   "lora-server.messages-appended/lora-server.uplink-packets-rx": [     {       "value": "100"     }   ] } Thanks for any help.
