Disable Tracking of Files in a Java Application

Overview of the Issue
Steps to Resolve the Issue

Overview of the Issue

This issue occurs in one of the following scenarios:

An organization runs a Java Application that is impacted by high CPU and Memory when adding the vFunction Agent. The Application creates a large number of Files when instrumented, as seen in the vFunction Analysis' Resources Report

Steps to Resolve the Issue

Take the following steps to resolve this issue:

SSH or RDP to the VM running the Application where the vFunction Agent is installed
Modify the native-conf.json either before or after running the installation script

Before the Installation Script

### Using SED
sed -i 's~#tracking_conf~tracking_conf~g' /opt/vfunction/controller-installation/stuff/agent/java/native-conf.json
sed -i 's~"files": true~"files": false~g' /opt/vfunction/controller-installation/stuff/agent/java/native-conf.json

### Linux Sudo / Root Installation
vi /opt/vfunction/controller-installation/stuff/agent/java/native-conf.json

### Linux Sudoless Installation
vi $BASE_DIR/opt/vfunction/controller-installation/stuff/agent/java/native-conf.json

### Windows Installation
$BASE_DIR\\vfunction\\controller-installation\\stuff\\agent\\java\\native-conf.json

{
    "#disable_thread_following": true,
    "#stack_sampling": false,
    "#sampling_ring_size": 256,
    "#disable_agct": true,
    "#disable_console_logging": true,
    ### Remove the comment in front of tracking_conf
    "tracking_conf": {
        "sockets": true,
        ### Change files from TRUE to FALSE
        "files": false,
        "sync_objects": true
    },
    "#static_root_classes": {
        "inclusions": [
            "Lcom/example/OneClassToInclude;",
            "Lcom/example/package1/"
        ],
        "exclusions": [
            "Lcom/example/"
        ]
    },
    "#force_resolve_on_unload": true
}

After the Installation Script

### Using SED
sed -i 's~#tracking_conf~tracking_conf~g' /etc/sysconfig/vfunction/agent/instances/$INSTANCE_NAME/native-conf.json
sed -i 's~"files": true~"files": false~g' /etc/sysconfig/vfunction/agent/instances/$INSTANCE_NAME/native-conf.json

### Linux Sudo / Root Installation
vi /etc/sysconfig/vfunction/agent/instances/$INSTANCE_NAME/native-conf.json

### Linux Sudoless Installation
vi $BASE_DIR/vfunction/etc/sysconfig/vfunction/agent/instances/$INSTANCE_NAME/native-conf.json

### Windows Installation
$BASE_DIR\\vfunction\\controller-installation\\stuff\\agent\\java\\native-conf.json

{
    "#disable_thread_following": true,
    "#stack_sampling": false,
    "#sampling_ring_size": 256,
    "#disable_agct": true,
    "#disable_console_logging": true,
    ### Remove the comment in front of tracking_conf
    "tracking_conf": {
        "sockets": true,
        ### Change files from TRUE to FALSE
        "files": false,
        "sync_objects": true
    },
    "#static_root_classes": {
        "inclusions": [
            "Lcom/example/OneClassToInclude;",
            "Lcom/example/package1/"
        ],
        "exclusions": [
            "Lcom/example/"
        ]
    },
    "#force_resolve_on_unload": true
}

If steps taken before the installation, run the installation script
Restart the JVM
